    Study Notes

    DNA Replication

    • Helicase is the enzyme responsible for unwinding the DNA during replication

    Function of Single Strand Binding Proteins

    • Single strand binding proteins bind to the single-stranded DNA, preventing secondary structure formation and protecting it from degradation during DNA replication

    Initiation of DNA Replication in Prokaryotes

    • DNA replication starts at a single origin of replication in prokaryotes

    Semiconservative Model of DNA Replication

    • The semiconservative model of DNA replication states that each new double strand consists of one old strand (from the parent molecule) and one new strand synthesized during replication

    Role of ATP in DNA Replication

    • ATP provides energy for the process of DNA replication

    Models of DNA Replication

    • The semiconservative model states that each double strand consists of one parental strand and one new strand
