If one compares the base sequences of related genes from different species, one is likely to find that corresponding ________ are usually conserved, but the sequences of ________ are much less well conserved.
A) exons; introns
B) introns; proteins
C) introns; exons
D) chaperons; exons
E) introns; chaperons

Exons are the coding regions of genes that are typically conserved across species because they encode proteins essential for biological functions. Introns, on the other hand, are non-coding regions that are less conserved as they do not directly affect the protein sequence.
