Which of the Following is Not Associated with MRNA Processing

Question

Which of the following is not associated with mRNA processing in eukaryotes?
A)addition of a 5' methyl guanosine cap
B)3' polyadenylation
C)removal of introns
D)removal of exons
E)removal of exons and introns

Accepted Answer

Removal of exons is not associated with mRNA processing in eukaryotes. Instead, mRNA processing involves the addition of a 5' cap, 3' polyadenylation, and the removal of introns, not exons. Exons are the coding sequences that are retained and spliced together to form the mature mRNA.
