The nucleotide sequences on DNA that actually have information encoding a sequence of amino acids are:
A)introns
B)exons
C)proteins
D)enhancers

Question

Quizplus · Accepted Answer

Exons are the nucleotide sequences on DNA that contain the coding information for proteins. Introns are non-coding sequences that are removed from the mRNA before translation. Enhancers are regulatory sequences that bind to transcription factors to regulate gene expression. Proteins are the end product of translation and are not themselves nucleotide sequences on DNA.
