Question

Match the following and choose the correct option

A. Capping	I. Association of RNA polymerase with (ρ) factor
B. Tailing	II. Removal of introns
C. Splicing	III. Methyl guanosine triphosphate added to 5’ end of hnRNA
D.Termination	IV. Addition of adenylate residues

• A. A-I, B-III, C-II, D-IV
• B. A-II, B-I, C-IV, D-III
• C. A-II, B-III, C-IV, D-I
• D. A-III, B-IV, C-II, D-I

Answer 1

The correct option is D A-III, B-IV, C-II, D-I

In eukaryotes, the process of transcription leads to the formation of a heterogeneous nuclear RNA (hnRNA) which undergoes the following changes.

* Capping of hnRNA is the addition of methyl guanosine triphosphate to the 5’ end.

* Tailing is the addition of adenylate residues at the 3' end of hnRNA.

* Splicing is the removal of introns from the hnRNA.

In prokaryotes, termination of transcription is achieved with the association of RNA polymerase with (ρ) factor.
