Question

​ Protein helping in opening of DNA double helix in form of replication fork is a) DNA gyrase b) DNA polymerase 1 c) DNA ligase d) DNA topoisomerase

Answer 1

Answer is DNA polymerase

Answer 2

The protein that helps in the opening of DNA ‘double helix’ in the form of the replication fork is a) DNA Gyrase.

The ‘DNA Gyrase’ is an enzyme that belongs to the family of Topoisomerases. It is an ATP dependent enzyme that reduces the ‘negative supercoiling’ of the DNA thereby controlling the stress during replication.

Generally, when designing antibiotics they majorly target the DNA Gyrase of the organism so that to control replication and cell division.
