In the eukaryotic cell,the coding sequences on a gene are referred to as
A) exons.
B) operons.
C) introns.
D) promoter.

Question

Quizplus · Accepted Answer

Exons are the coding sequences on a gene that are transcribed into mRNA and translated into proteins. Introns are noncoding sequences that are transcribed into mRNA but then spliced out, while operons are found in prokaryotic cells and consist of multiple genes under the control of a single promoter. Promoters are DNA sequences that initiate transcription of a gene. Therefore, the best choice is A) exons.
