MCQ
DNA replication is aided by:
- ADNA polymerase only
- BDNA ligase only
- CBoth DNA polymerase and ligase
- DRNA polymerase
✓
Answer
- Both DNA polymerase and ligase
Explanation:
DNA polymerase catalyes the formation of DNA strand. DNA ligase is otherwise called as molecular sutures. 5'→3' strand synthesis happens with the help of DNA Polymerase I. Synthesis of strand in 3' → 5' strand happens by the formation of okazaki fragments. These fragments are further joined together by the action of DNA ligase enzyme.
