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.

The recessive mutant allele that causes cystic fibrosis is much more frequent in Caucasians population than in other world populations. Some scientists believe heterozygotes must have had a survival advantage during plagues such as cholera that occasionally swept through this population. What concept does this illustrate?
