In Eukaryotes, mRNA is supplemented with a sequence of adenine nucleotides (poly A tail) at one end and methylated guanine nucleotides at the 5’ end (cap). This is occurs
A. Just before transcription.
B. Just after transcription, in the nucleus.
C. Just after transcription, in the cytoplasm.
D. Just before translation in the cytoplasm.
Homework Answers
in eukaryotes transcription occurs in the nucleus and post-transcriptional modifications like polyadenylation, splicing also occurs in the nucleus.
5` Cap is added to the RNA during transcription, after the first few nucleotides in the RNA is added the 5` Cap is added.
once the RNA is transcribed the 3` end of the RNA is cleaved after AAUAAA and polyA is added by the enzyme poly-A polymerase.
so these modifications occur after transcription so the answer is B) just after transcription, in the nucleus.
