Processing of mRNA includes __________(a) 5′ capping, 3′ polyadenylation and RNA splicing(b) 3′ capping, 5′ polyadenylation and RNA splicing(c) 5′ capping and 3′ polyadenylation(d) 5′ capping and RNA splicingThe question was posed to me during an online exam.Origin of the question is Nucleus topic in chapter Nucleus & Aerobic Respiration of Cell Biology

Answer»

The CORRECT answer is (a) 5′ capping, 3′ polyadenylation and RNA splicing

Explanation: After transcription, the pre-mRNA is modified to produce matured mRNA. The MODIFICATION of mRNA INCLUDES the following- 5′ methul GUANOSINE capping that protects the mRNA from RNases, 3′ polyadenylation and splicing of the introns of pre-mRNA.
