Question

Which of the following statement is most correct in DNA replication

• A. Helicase enzyme separates the two strands, DNA gyrase helps in opening of DNA double helix in front of replication fork and Tus protein helps in termination of replication
• B. DNA polymerase enzyme separates the two strands, DNA gyrase helps in opening of DNA double helix in front of replication fork and Tus protein helps in termination of replication
• C. Helicase enzyme separates the two strands, DNA ligase helps in opening of DNA double helix in front of replication fork and Tus protein helps in termination of replication
• D. DNA ligase enzyme separates the two strands, DNA gyrase helps in opening of DNA double helix in front of replication fork and topoisomerase helps in termination of replication

Hint:

Remember the three key replication enzymes and proteins: Helicase unwinds, Gyrase relieves supercoiling strain ahead of the fork, and Tus terminates replication by binding to Ter sites.

Answer 1

The Correct Option is A
