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

Question

Quizplus · Accepted Answer
