Question

Quizplus · Accepted Answer

Noncoding regions of RNA are called introns. In contrast, exons are the coding regions that are ultimately expressed as proteins. Precursor RNA refers to the initial transcript that contains both introns and exons, which will be processed to generate the final mRNA molecule. Nonsense RNA is a type of RNA that does not code for any protein sequence and is typically degraded. Empty RNA is not a recognized term in molecular biology.
