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.
