    DNA can be formed by

    A)  transaminase

    B)  lyases

    C)  RNA dependent DNA polymerase

    D)  All of the above

    Correct Answer: C

    Solution :

    During DNA replication, enzymes DNA dependent DNA polymerase, primase and  ligase are used, while RNA dependent DNA  polymerase synthesizes DNA from RNA during  reverse transcription. Transaminase catalyses the transfer of an amino  group from one molecule to another. They play important role in the synthesis of  amino acids, while RNA dependent DNA polymerase synthesis DNA from RNA during  verse transcription. Lyases remove a group from substrate (not by hydrolysis).
