If scientists find dinosaur DNA, analyzing
it is a major challenge.
Scientist must extract the DNA (separate it
from proteins), make copies of it, and determinine
the sequence. All of these steps could lead to
contamination or loss of the sample.
Once the sequence in DNA is known it can be
compared to known sequences of animals alive
today. These comparisons can inform scientist of
how closely related species are and how animals
evolved. If the identified sequences are in genes
that encode proteins, scientist may be able to
determine the structure of dinosaur proteins. For
example,do dinosaurs have genes that encode
proteins for making pigment? Perhaps this
could give scientist an idea of dinosaur color.
