DNA Replication

DNA replication is semi conservative type it means in newly formed DNA one strand is new and another is old. Helicase enzyme opens both strand of DNA. Topoisomerase stop torsion. RNA primer starts adding nucleotides in 5 to 3 direction. Continuous strand is known as leading strand and discontinuous is lagging strand. Gaps are filled by DNA ligase enzyme. RNA polymerase enzyme stops replication process.
