Match list\[\text{-I}\] and list\[\text{-II}\] and select the correct answer using the code| S. No. | List\[\text{-I}\] (Enzyme) | List\[\text{-II}\] (Enzyme function) |
| 1. | Ligase | Joins short segment of DNA together |
| 2. | DNA Polymerase | Cuts DNA at specific DNA sequence |
| 3. | Helicase | Breaks the hydrogen bonds between complementary pairs during DNA replication |
A) 1, 2 and 3 are correct
B) 1 and 2 are correct
C) 1, 2 and 4 are correct
D) 1 and 3 are correct
Correct Answer: D
Solution :
Ligase or synthetase enzymes form bonds to join two molecules together, using energy supplied from the breakdown of ATP e.g., DNA ligase is used to repair breaks in DNA molecules. The main function of Helicase is break the hydrogen bonds between complementary pair during DNA replication.
