D)Genome duplication followed by exon shuffling

Question

Quizplus · Accepted Answer

Genome duplication followed by exon shuffling is the most likely mechanism through which proteins can acquire novel domain architectures over evolutionary time. Genome duplication provides an opportunity for genes to evolve new functions through mutations, while exon shuffling allows for the rearrangement of existing genetic information to create new combinations of domains. Together, these mechanisms can create novel protein architectures that may confer adaptive advantages in varied environments.
