An enzyme which can convert single stranded RNA into double stranded viral DNA is called____________?
Correct answer: D. Reverse Transcriptase
- A. DNAase
- B. RNAase
- C. DNA polymerase
- D. Reverse Transcriptase
Explanation
Reverse transcriptase uses an RNA template to synthesize complementary DNA and can ultimately produce double-stranded viral DNA. DNAase and RNAase are nucleases that degrade nucleic acids, while ordinary DNA polymerase does not normally copy RNA into DNA.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
