Which of the following is most highly conserved in a comparison between distantly related species (e.g.a fish and a primate)?
A) 3'UTR
B) 5'UTR
C) protein-coding sequences
D) introns
E) intergenic regions

Question

Quizplus · Accepted Answer

Protein-coding sequences are most highly conserved among distantly related species as they are essential for carrying out the same functions in different organisms. Mutations in these sequences could potentially harm important biological processes, so they tend to be conserved through evolution.
