The theory goes that mutation is the raw material for evolution. Existing sequences of DNA, some of which codes for functional proteins, other sections dont, have random changes in their nucleotide sequence over time, that may persist and dawn reproductive advantage onto carriers of that gene.
I know that changes in the nucleotide sequences of the same gene have been observed across species, like in the genes that code for polypeptides in cytochrome C and hemoglobin. Based on this evidence a sort of evolutionary time line can be developed to show how far back organisms diverged from a common ancestor by comparing the numbers of differences in nucleotide sequence. In the study of genomes thus far, is there any evidence that suggests a related sequence of nucleotides that result in different functional proteins? Not all organisms have the same proteins, so wouldnt we expect to find that when we find a novel protein on the evolutionary tree, that the nucleotide sequence that codes for that protein would be analogous or similar to a the sequence for a different functional protein? I havent come across anything on this front and was wondering what the experts know. Thanks and I hope you have lots to be thankful for! Sincerely, Bret Klopfenstein Ventura HS

In the answer to a question about ethyl alcohol and bacteria you-all wrote that ethyl alcohol can kill bacteria because it denatures the proteins in the cell and dissolves the cell membrane. I am trying to figure out how the ethyl alcohol in handgel affects viruses. I have read that all viruses have a protein coat that protects their genetic material and some have an envelope of fat that surrounds them. If the virus coat/shell is made up of proteins and /or fat if ethyl alcohol denatures the proteins in a bacterium cell, does it also denature the proteins and/or fat that make up the virus coat? If it does this, is this the reason we could say that hand gel is effective in killing viruses that may get on your hand?

I'm asking for help with the assistance of my teacher. I'm doing a science fair and research project on the golden ratio in nature. I'm interested in mathematics and finding relationships between things I can measure in the real world.
I've been doing research on the golden ratio and I've found that the information is either too general or too advanced. I think there may be two ways you could help me:
1. I would like some help finding material that could help inform me appropriately (beyond the junior high level, but easier than graduate school) for my mathematical research.
2. Is it possible that there might be someone on campus willing to mentor me?
Teacher's note: This student is one of the brightest girls I've seen! Worth nurturing/Mentoring!!!!

I am doing a project on DNA sequence and on how changes in the sequence cause disorders. For example, cystic fibrosis is caused by a recessive allele. When you look at that string of DNA you can see there are three DNA bases missing. Here are my questions I need answered:
1) What kind of technology you would use when looking for the DNA impurities?
2) In the sequences is it easy to point out the mistakes or are they hard to see?
3) Is a specific name for this action or do I just call it DNA sequencing?
4) Is it possible to replace the mistakes with the correct sequence? --Thank you

|533: ||In Psychology, it is a well known fact that one can change oneself through positive self- affirmation & visualization .It is believed that the self-affirmations to the subconscious mind are best done in an already achieved mode. For example, a student who is weak in mathematics and wish to improve on it should say the self- affirmations as I am excellent at mathematics & also visualize himself as ALREADY being good at Math repeatedly. Or a person who is a coward could reprogram his mind by saying to himself, I am brave, etc. This is so that the subconscious mind is set with the positive intended goal and thus will program the whole body with the message. But the question is that such self-affirmation is not the truth (or not the truth yet). When he is telling himself that he is ALREADY being good at Math, he is actually lying to himself. So, would it better to say,I am getting better and better at Math rather than I am excellent at Math?

would seem impossible. OR, is there one rate of
life in all the universe? It seems that this
would have to be the case for any contact to
occur since the probability of another species'
"rate of life" being close to ours appears to be
zero. Do you think our rate of life is connected
to the speed of light. So, for example, an alien
species with a rate of life one hundred times

Hello, I am a current intern at Nationwide
Children's Hospital in Columbus Ohio and I am
having some trouble with teaching myself some
cell signaling pathways for microbial
pathogenesis. I taught myself the three
complement pathways to destroy pathogens through
the use of C5bC78 added to around 10-16 C9s to
make a MAC, but I am trying to teach myself the
toll-like receptor pathways and others like
that. I am very much a visual learner but these
pictures that I am getting online are too
complex for me to decipher. Also, the videos
online that I am finding are too simple and I
need to go more into depth. I have a
presentation of what I did in the lab for the
past few months coming up on August 10th and I
need to be as well prepared as I can be because
a scholarship is on the line that I am competing
with other students for and it is vital that I
am well prepared to be as versed as I can be in
the topic of microbial pathogenesis and
immunology. Are there any sites or books
that you would recommend me looking for? I would
really like help here! Thanks so much.

I have a question about the genetic
similarities between the major primate species
(orangutans, chimpanzees, gorillas, gibbons, and
bonobos) and humans. A lot of times one hears
about how humans and chimps are the closest to
each other genetically, differing in their
genetic makeup by only a few percent. I´m
wondering though, how close genetically are the
great apes to each other?
For example, how close are chimps to
gorillas, gibbons, or bonobos? Or gorillas to
orangutans, etc.? Do you guys know of any
references comparing the genetic codes of all of
the great apes to humans (from which I could
deduce how similar the great apes are from
themselves)? Or perhaps a direct comparison of
primate genetic codes to each other? I´m mostly
interested in the overall percentage difference
between each species, but I´d love to look at
any additional information as well such as where
their genetic codes differ with regard to each
Any help or references to resources on the
subject would be greatly appreciated! Thanks!

I am in 8th grade and I\'m starting to work on
science fair project. The question for my
How does sight affects taste?
I will test that by having 3 equal amounts of
drinks in clear cups. One will be cherry, one
be grape and one will be lemon/lime. The
volunteers will first taste each drink and try to
guess the flavors. Next, I will blindfold the
volunteers and have them guess again. Then I will
add food coloring to the drinks to make the
look like grape, lemon/lime look like orange and
grape look like root beer or cocoa cola. The
volunteers will then test each drink and tell me
what they think each flavor is. My hypothesis is
that on the control and blindfolded test, most
people will guess correctly. On the incorrect
colored test, I think people will guess the
to be grape, the lemon/lime to be orange and the
grape to be coca cola.
a. Do you think that the procedures should
differently in order to answer my question (How
does sight affects taste)?
b. Do you think the colors of each flavor
difference, or should I change them?
c. Do you think my hypothesis is correct?
d. Is there anything important that I need
before I start conducting the experiment?
e. How many volunteers do you think I
to make the experiment reliable?
f. How do you think I should graph this

deal with, and should I make it to just one

effects taste that you think is important to
conduct this experiment?

Dear UCSB Researchers, I am an 8th grade
student hoping to research methods of resisting
bordetella pertussis disease. I was thinking that
if there was a vaccine that would increase the
growth of cilia on our ciliated epithelial cells
in our respiratory system, then we would be more
protected from whooping cough. Would you think
this could be a good hypothesis? "If our
epithelial cells in our respiratory system produce
continuous amounts of cilia, then our bodies will
be more protected from bordetella pertussis." I
see two possible questions to study:
1. Is there a chemical that can grow more cilia
on lung cells?
2. What can I use as a safe substitute that is
just like bordetella pertussis?
I think that pertussis is too dangerous to use
as a bacterium, so what would you recommend as a
substitute? Also, how could I grow these cells at
my home without a lab? Is there a way I can grow
more cilia on cells? How could I actually measure
how many cilia are present (would I take a picture
and count)? Thank you! From an 8th grade

I read an article attempting to explain why
viruses attack cells. The argument mentioned by
the author hinges around the idea that a virus is
genetically programmed to attack cells. We
already know that. What is missing is how this
viral genetic code was written in the first place.
This is not a philosophical question!
The point is as follows: evolution is an
ongoing biological process and different life
forms are different form one another. Having said
that, it is not clear how the genetic make-up of a
virus can be designed in order to successfully
attack cells. Consider the differences between a
bacteriophage and the Human Immunodeficiency Virus
(HIV). Clearly, they have different structural
properties that allow them to successfully invade
the corresponding targets. Why? How did it
happen? What are the fundamental mechanisms
underlying viruses, i.e., design and build a virus
that will be able to infect the following cell?

In the beginning of this experiment, I
hypothesized that Classical music would lower the
heart rate and blood pressure by releasing greater
amounts of Serotonin into the bloodstream. I also
hypothesized that Rap, or any high-temped music,
raises norepinephrine levels.
My studies have shown that this is true, but
not in every case. 50% of my subjects’ blood
pressure rose while listening to rap, but the
other half did not, instead staying neutral e or
even lowering. 75% of the subjects’ blood pressure
decreased with Classical music, but the effects
were not as drastic. 50% of the subjects enjoyed
rap, which is probably the cause of the lowered
blood pressure. 50% enjoyed classical music, or
knew the song, which is why their blood pressure
lowered. The heart rates of all the subjects made
no pattern during this experiment, except after
the classical music was played. In conclusion to
my experiment, I realized that whichever genre of
music you enjoy lowers the blood pressure, not due
to the rhythm.
Can you relate to my conclusion? Do you think it
is accurate? Thank you so much!

I wonder this because how else could inanimate
material come alive, and I once read that the
Earth is alive itself, leading me to believe that
Earth could have been the first producer. I still
wonder how the Earth would have come alive itself,
but I theorize the electrical forces of atoms and
specific molecules pulling or pushing themselves
together or apart, as well as the natural movement
of heated atoms, along with the already present
forces of Earth's spin and movement produced by
the big bang could have caused the inanimate Earth
to begin "come alive." The original moving up of
iron (or whatever element was attracted to
another) from inside Earth could have led to a
chain of reactions that led to more chains of
reactions, and so forth, so that a never-ending
push and pull were then created via the original
electrical attractions. I realize this is a
complex idea and a far-fetched question, but I
found your website and thought I'd ask. Thanks

there are only 23 chromosomes, haploid, not in

karyotype to see the pair of \"l\").
My question #1 is: When I see the pair of

looking at non-sex cells?
Question #2: Which karyotype will you use to
determine a disorder?
To answer my own question, I think - since all
the DNA is the same in every cell, the unknown
genes wouldn't matter which cell you would look
at, but if you are looking for Turner's Syndrome,
then you would have to use a Somatic cell. Or
does it really not matter if you have somatic cell
autosome; which karyotype picture would I look

I will appreciate it if someone looks over the following calculation. Thank you! So I've heard that bananas have tiny amounts of radiation in them, due to potassium, and if you eat too many bananas you can die of radiation poisoning. Of course the next logical step is to ask the question, how many bananas do I need to power my house? We start by getting two values, the radiation energy emitted by a banana and the amount of electricity the average American house needs. According to Wikipedia, a banana emits .1 microsieverts of radiation. According to the US department of energy the average American household uses 893 KWH a month. Therefore we just have to convert 893 KWH into its equivalent in microsieverts, multiply by 10, and get the amount of bananas required to power the average American house for a month.
893 KWH = 3.66 joules, one sievert is equal to 1 joule of energy, therefore we require 3.66 sieverts, which is 3.612 microsieverts, multiply by ten is 3.613 microsieverts, which means that it takes 3.613 bananas to power the average American household for a month. (That's a lot of bananas)Thank you for reading this calculation. It's probably wrong (the joule to sievert conversion is really iffy). Please correct me on any errors. Thank you :)
