In the structure of many eukaryotic genes, individual exons parallel which of the following?
A) the sequence of the intron that immediately precedes each exon
B) the number of polypeptides making up the functional protein
C) the various domains of the protein product
D) the number of start sites for transcription

Question

Quizplus · Accepted Answer

Exons often correspond to the various domains or functional segments of the protein product, reflecting the modular structure of many proteins. Each exon can encode a specific portion of the protein, allowing for complex protein structures to be assembled from different combinations of exons through processes like alternative splicing.
