Options

(a) DNA gyrase
(b) DNA ligase
(c) DNA polymerase I
(d) DNA topoisomerase I

Correct Answer:

DNA gyrase

Explanation:

Deoxy Ribo Nucleic gyrases are the type of class II topoisomerases, it helps to open the DNA double helix in front of the DNA. DNA polymerases it involved in the synthesis of a new DNA strand. The DNA ligases joined to the nicks presents in between the Okazaki fragments.
