Which of the following does not occur during the processing of eukaryotic mRNA?
A
Polyadenylation at the 3' end
B
Removal of introns
C
Replication of mRNA
D
Addition of a 5' cap
Verified step by step guidance1
Understand the process of eukaryotic mRNA processing, which involves several modifications to the pre-mRNA before it becomes mature mRNA.
Learn about polyadenylation, which is the addition of a poly(A) tail at the 3' end of the mRNA. This process helps stabilize the mRNA and facilitates its export from the nucleus.
Explore the removal of introns, a process known as splicing. Introns are non-coding regions that are removed from the pre-mRNA, leaving only the exons, which are the coding sequences.
Examine the addition of a 5' cap, which is a modified guanine nucleotide added to the 5' end of the mRNA. This cap protects the mRNA from degradation and is involved in the initiation of translation.
Identify that replication of mRNA does not occur during mRNA processing. Replication refers to the copying of DNA, not mRNA, and is not part of the mRNA processing steps.
