Question

Which of the following lists the molecular events of a coronavirus infection in the correct order?

A. translation of viral proteins, transcription of viral RNAs, virus particle assembly

B. reverse transcription of viral genome, translation of viral RNAs, virus particle assembly

C. integration of viral genome into host genome, transcription of viral RNAs, translation of viral proteins

D. DNA polymerase replicates viral genome, transcription of viral RNA, virus particle assembly

E. More than one answer is correct

Answer 1

The correct order is given in A

The correct order is as:

1. Upon entering into the host cell the RNA of the virus is translated to give RNA Dependent RNA Polymerase (RDRP) enzyme.

2.This RDRP enzyme causes the replication of viral RNA to give it's complementary strand.

3. This strand is then translated to synthesise other proteins necessary for the assembly of the virus particle.

Other options are incorrect because

There is no reverse transcription, no integration of viral genome into host genome, and no use of DNA polymerase as it is an RNA virus.
