Question

Accumulation of favorable mutations is the basis for evolution. Relate the error-prone nature of SARS-CoV-2 RNA replication machinery to the transmissibility of COVID-19 patients

Answer 1

Ans - Accumulation of favourable mutations is the basis for evolution as mutations are raw material for genetic variation . A mutation is nothing but a change in DNA sequence , which is the hereditary Material of life. So it is like change in organisms DNA can cause changes in all aspects of life . Therefore mutations are found to be essential for evolution , without mutation evolution cannot occur.

Error prone nature of SARS-CoV -2 RNA replication machinary is related to transmissibility of COVID-19 patients as this virus is asymptomatic virus , hence its shedding is found to raise the possibility of transmission from asymptomatic carriers to other people.
