Answer:
Option). DNA ligase.
Explanation:
DNA ligase is a specific enzyme that connects (ligates) fragments of DNA together. They work by catalyzing phosphodiester bond formation between 3' hydroxyl group and 5' phosphate group of DNA.
DNA ligeases play roles in various processes, such as in joining the Okazaki fragments, sealing repairs in DNA, and sealing recombinant fragments.
Thus, the correct answer is option). DNA ligase.
