Question

The information carried by RNA in retroviruses is put in the DNA code by ?
  1. DNA polymerase
  2. DNA ligase
  3. RNA synthetase
  4. Reverse transcriptase

A
Reverse transcriptase
B
DNA polymerase
C
DNA ligase
D
RNA synthetase
Solution
Verified by Toppr

  • 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'.
