DNA Topology class 1: Topoisomerase

Role of Topoisomerase I and Topoisomerase II in DNA topology Topoisomerase is a class of enzyme which helps in winding and unwinding of DNA. Three forms of DNA is most prevalent in nature: circular, linear and supercoiled. Circular DNA is covalently closed and does not have any interruption in between nucleotides. Circular DNA is found in

DNA Replication class 1: General process of DNA replication

“Replication is an enzyme governed process, in which new DNA molecule is formed by the process of semi-conservative DNA replication.”¬† DNA replication is a process in which new DNA is formed (copying DNA). Four new single strands of DNA (2 double helix), are generated in a semiconservative manner of DNA replication. The basic mechanism of
