What Enzyme forms covalent bonds between Restriction fragments?

Question

Select the correct option:

What Enzyme forms Covalent Bonds between Restriction fragments?

1. DNA primase
2. DNA helicase
3. single-stranded binding protein
4. DNA polymerase
5. DNA ligase

Answer 1

5. DNA ligase

DNA ligase is the enzyme that forms Covalent Bonds between Restriction fragments.

---

Explanation:

The enzyme DNA ligase joins the two DNA molecules by covalent bonds. This enzyme, which the cell normally uses in DNA replication is a DNA pasting enzyme that catalyzes the formation of covalent bonds between adjacent nucleotides, joining the strands.

The result is a recombinant DNA plasmid.
