Gene Sequences That Remain Very Similar Over Many Species Are

Question

Gene sequences that remain very similar over many species are said to be
A)the same.
B)noncoding regions.
C)highly conserved.
D)of the same family.
E)resistant to mutation.

Accepted Answer

Sequences that remain very similar over many species are said to be highly conserved. This implies that the sequence has been preserved throughout evolution because any changes that might affect the function of the gene have been weeded out by natural selection. Highly conserved sequences are usually important for the survival or reproduction of an organism.
