Which term refers to the expressed portions of a gene that code for proteins?

Explanation:
Exons are the expressed portions of a gene that code for proteins. In genes, exons and introns are initially transcribed, but introns are removed during RNA processing while exons are joined to form the mature mRNA. This mature mRNA is then translated into a protein. Promoters regulate where transcription starts and aren’t part of the final mRNA, while untranslated regions (UTRs) are transcribed but not translated into protein; they help regulate translation and mRNA stability. So the protein-coding, expressed segments are the exons.
