Which answer correctly compares the primary transcript in the nucleus of a eukaryotic cell with the functional mRNA?
A) the primary transcript is the same size as the mRNA
B) the primary transcript is larger than the mRNA
C) the primary transcript is smaller than the mRNA
D) both the primary transcript and mRNA contain introns

Question

Quizplus · Accepted Answer

The primary transcript in a eukaryotic cell, also known as pre-mRNA, is larger than the functional mRNA because it includes both introns and exons. During RNA processing, introns are removed, and exons are spliced together to form the mature mRNA, which is then smaller than the original primary transcript.
