DNA gyrase, often referred to simply as gyrase, is an enzyme that relieves strain while double-strand DNA is being unwound by helicase. It is also known as DNA topoisomerase II.This causes negative supercoiling of the DNA.his process occurs in prokaryotes (in particular, in bacteria), whose single circular DNA is cut by DNA gyrase and the two ends are then twisted around each other to form supercoils. Gyrase has been found in the apicoplast of the malarial parasite Plasmodium falciparum, a unicellular eukaryote.
What is the function of helicase in DNA replication? A- It joins together Okazaki fragments. B- It untwists the double helix and separates the two DNA strands. C- It adds nucleotides to the new strand in the 5' to 3' direction. D- It checks for errors in the newly synthesized DNA strand. E- It relieves strain from twisting of the double helix as... show more A- It joins together Okazaki fragments. B- It untwists the double helix and separates the two DNA strands.
