Solution
The correct option is C Retrovirus
- H. Temin and D. Baltimore showed that the retroviruses namely the Rous sarcoma virus and the AIDS virus can make an RNA-dependent DNA polymerase that synthesizes a DNA copy (cDNA) of viral RNA.
- The cDNA is made into a double-stranded molecule which is integrated into a host genome where it is replicated and transcribed with host DNA; the topsy curvy path of flow of genetic information, i.e., RNA-DNA-RNA-protein.
- The enzyme was termed as reverse transcriptase. Rhinovirus, dengue virus, and herpes viruses are not retroviruses and follow the linear path of flow of genetic information DNA-RNA-protein
So, the correct answer is 'Retrovirus'
