The nucleotide sequence in the mRNA that does not code for part of a protein is a(n)
A)intron.
B)exon.
C)heterogenous nuclear RNA.
D)gene.

Question

Quizplus · Accepted Answer

The non-coding region of mRNA is called an intron. Exons are the coding regions that are expressed in the protein sequence. Heterogeneous nuclear RNA (hnRNA) refers to pre-mRNA, which includes both exons and introns before RNA splicing occurs. A gene refers to a unit of hereditary information that codes for a specific protein or RNA molecule.
