Question

The information carried by RNA in retroviruses is put in the DNA code by ?

• A. DNA polymerase
• B. DNA ligase
• C. RNA synthetase
• D. Reverse transcriptase

Answer 1

The correct option is D Reverse transcriptase

• Reverse transcriptase enzyme is an enzyme that is used to generate cDNA from RNA template through the reverse transcription process. This is seen in many retroviruses to replicate their genomes.
  
• DNA polymerase enzyme helps in DNA synthesis using DNA template, a process called replication.
  
• DNA ligase is used to join DNA fragments during DNA repair or its replication.
  

So, the correct option is 'Reverse transcriptase'.
