1.	Which enzyme removes the positive supercoils generated when the replication fork?(a) helicase(b) endonuclease(c) exonuclease(d) gyraseThe question was asked in a national level competition.My question is taken from DNA Replication in chapter DNA Replication and Repair, Cellular Reproduction of Cell Biology
Answer» Right CHOICE is (d) gyrase Easiest explanation: DNA gyrase is an enzyme BELONGING to the topoisomerase-II type of ENZYMES. The basic function of DNA gyrase is to relieve the mechanical stress and the POSITIVE supercoils that BUILD up during replication.
