What information can be gained by comparing the sequences of proteins that have the same or similar function in different species?
A)To determine evolutionary relationships and relatedness of species.
B)To determine sequences that are conserved among species since they are likely to be important to the function and stability of the proteins.
C)To locate highly variable residues which contribute little to the structure and function of the protein.
D)All of the above.

Quizplus · Accepted Answer

Comparing the sequences of proteins that have the same or similar function in different species can provide information on evolutionary relationships and relatedness of species (A), identify sequences that are conserved among species which are likely important to protein function and stability (B), and locate highly variable residues which may not contribute significantly to the structure and function of the protein (C). Thus, all of the above (D) is the correct answer.
