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
