Detailed explanation-1: -The 5’ cap structure m7GpppN (where N is any nucleotide) is a ubiquitous feature of cellular eukaryotic mRNAs. The cap is multifunctional as it is involved in translation, nucleocytoplasmic transport, splicing, and stabilization of mRNA against 5’ exonucleolytic degradation.
Detailed explanation-2: -The 5’ cap protests the newly-synthesized mRNA from degradation. It also assists in ribosome binding to help initiating translation.
Detailed explanation-3: -5’ End Capping At the end of transcription, the 5’ end of the RNA transcript contains a free triphosphate group since it was the first incorporated nucleotide in the chain. The capping process replaces the triphosphate group with another structure called the “cap". The cap is added by the enzyme guanyl transferase.
Detailed explanation-4: -Which of the following is not part of RNA processing in eukaryotes? Reverse transcription is the enzymatic synthesis of DNA from an RNA template by the enzyme reverse transcriptase. This enzyme is not involved in the RNA processing reactions.
