C) exon shuffling
D) peptide shuffling
E) exon splicing

Question

Quizplus · Accepted Answer

Exon shuffling is a molecular mechanism by which new proteins can evolve. It involves the recombination of exons, which are the coding sequences in genes, leading to the creation of new proteins with novel combinations of functional domains. This process can introduce a new protein domain into a pre-existing protein, thereby potentially altering its function or adding new capabilities.
