What is the sequence of the protein present in the last common ancestor of humans and chimpanzees?
sequence:
ATSAAGWDEWEGGKVLIHILDGKLQNRGALIELDIGAV
Incorrect Answer
<Feedback
Sorry, that's incorrect.
You have not identified the sequence of
the last common ancestor of humans
and chimpanzees. Make sure that you
enter the entire sequence and not just
the parts of the sequence that are
different. Consider that the orangutan
protein diverged prior to the common
ancestor. Note that, like the
chimpanzee protein, the orangutan
protein contains W at position 7.
Additionally, the orangutan protein
contains V at position 15 as is observed
in the human protein.
