Which of the following does not occur before a eukaryotic mRNA is exported from the nucleus?
A
Polyadenylation at the 3' end
B
Splicing of introns
C
Addition of a 5' cap
D
Translation into protein
Verified step by step guidance1
Understand the process of mRNA processing in eukaryotic cells, which includes several modifications before the mRNA is exported from the nucleus.
Recognize that polyadenylation at the 3' end involves adding a tail of adenine nucleotides to the mRNA, which is crucial for stability and export.
Identify that splicing of introns is the removal of non-coding sequences from the pre-mRNA, allowing the exons to be joined together to form a continuous coding sequence.
Acknowledge that the addition of a 5' cap is a modification where a modified guanine nucleotide is added to the 5' end of the mRNA, which is important for mRNA stability and initiation of translation.
Realize that translation into protein occurs in the cytoplasm and not in the nucleus, thus it does not occur before the mRNA is exported from the nucleus.
