Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which process adds a Guanine to the 5’ end?
A
Polyadenylation
B
Splicing
C
Capping
D
Post transcriptional processing
Explanation: 

Detailed explanation-1: -During post transcriptional process, during the process of methyl gaunososine triphosphate is added to the 5’ end of the hn-RNA. This process is called capping. Q.

Detailed explanation-2: -(iii) An unusual nucleotide methyl guanosine triphosphate is added to the 5 end of hnRNA during capping.

Detailed explanation-3: -A 7-methylguanosine cap is added to the 5′ end of the pre-mRNA while elongation is still in progress. The 5′ cap protects the nascent mRNA from degradation and assists in ribosome binding during translation.
