Exons
A) are translated.
B) are found in most prokaryotic genes.
C) are removed during RNA processing.
D) provide RNA stability.
E) are added after transcription.

Question

Quizplus · Accepted Answer

Exons are the coding regions of genes that are transcribed into RNA and then translated into proteins. Therefore, they are translated.

Answer: C
 Exons are separated by non-coding introns, which are removed during RNA processing through a process called splicing. Therefore, exons are removed during RNA processing.

Answer: E
 Exons are not added after transcription. They are already present in the DNA and are transcribed into RNA.

Therefore, the best choice(s) is A and C.
