As well as synthesizing the transcript, RNA polymerase performs two proofreading functions on that growing transcript;

i. Pyrophosphorolytic editing

ii. Hydrolytic editing

Choose correct processes accordingly,

A. The polymerase backtracks by one or more nucleotides and cleaves the RNA product, removing the error-containing sequence.

B. In this, the enzyme uses its active site, in a simple back-reaction,

C. Catalyze the removal of an incorrectly inserted ribonucleotide, by reincorporation of PPi

D. The enzyme can then incorporate another ribonucleotide in its place in the growing RNA chain.
