Question

Two eukaryotic proteins have one domain in common but are otherwise very different. Which of the following processes is most likely to have contributed to this similarity?

a. gene duplication
b. RNA splicing
c. exon shuffling
d. random point mutations

Answer 1

The correct answer is option c. "exon shuffling".

Step-by-step explanation:

Exon shuffling is a molecular mechanism at which two or more exons from different genes are brought together and results in the formation of new genes. If two eukaryotic genes have one domain in common but are otherwise very different it is very likely that exon shuffling contributed to this similarly. Probably, the exon that encodes for the domain that the two proteins have in common was taken from one protein for the formation of the second one.
