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

Hi! For my science fair project I'm doing an
experimenting plant gravitropism, by growing
bean plants upside down, and three right side up.
I have some questions for you to please
1. For the upside down bean plants, I just put
seed in normally, however it still grew upwards.
The roots came out of the bottom of the fiber
starter pots, and the shoots burst through the
and grew upwards! I expected the plant grow down,
and then curve up.
2. What would have happened if the pot was clay?
Would the shoot have turned around when it
the top, and grow out the bottom?
3. What should I have done if I do the experiment
4. I know about negative and positive geotropism,
and I now feel bad for having expected it to grow
down and then up!
Thanks so much!- Natasha

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?

I was hoping that you would able to answer a
few quick questions I have about a project I am
thinking about doing for the BT young scientist.
1) Do different spectra of light effect the
growth of plants differently? (Ignoring green)
2) Do specific combinations of light i.e. red,
yellow and blue of an equal intensity to solar
light effect plants' growth?
3)Does the effectiveness of the light on
photosynthesis vary throughout the day? If so do
different spectra affect this?
The above questions are to aid in setting a
baseline for experiments, as I haven't been able
to find any definitive proof online.

We are growing rye grass and alfalfa in the dark
without any sunlight. Our classroom has no idea
how it is growing. It is growing faster than the
grass in the window. The grass getting sunlight
is a darker green, and the one in the dark is a
very light green, but it is taller. How come it
is growing without sunlight? We are going to keep
watering it and keep it in the dark to see what
happens. Will it keep growing? Please write back
or come visit us in room 8. We have lots of other
stuff growing too, like a sweet potato. Thank you!

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

buying different color light bulbs, either being
blue, red or green, etc.

read in certain sites, which say that to test this
theory, one needs to place the plant in front of
light sources such as Ultra-violet light,
