Which of the following events does NOT occur after the transcription of poly-A signal sequences into mRNA?
| 5 capping of the mRNA |
| degradation of the mRNA remaining associated with RNA polymerase by a 5 3 ribonuclease |
| cleavage of the mRNA releasing it from the RNA polymerase |
| addition of many adenine residues to the 3 end of the mRNA |
Solution
Answer: degradation of the mRNA remaining associated with RNA polymerase by a 5 3 ribonuclease
Degradation of mRNA will not takes place after transcription.
The major events post trancription are
1) 5\' capping of RNA
2) Polyadenylation at 3\'
3) Removal of introns.
