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) alternative splicing
C) exon shuffling
D) random point mutations

Question

Quizplus · Accepted Answer

Exon shuffling is a molecular mechanism that can create proteins with new combinations of functional domains, including cases where two proteins share a domain but are otherwise distinct. This process involves the recombination of exons, which are the coding sequences in genes, leading to the creation of new genes with novel arrangements of functional domains.
