What is the function of primase in DNA replication? What is the mechanism behind 5' - 3' exonuclease activity in DNA? What are the four roles that DNA must play in cells and how is the structure of DNA consistent with these roles?
Describe the function of DNA polymerase II in lagging strand synthesis in DNA synthesis. Describe the function of primase in opening the helix in DNA synthesis. (a) Define ligase. (b) Explain its role in genetic engineering. Explain the function of all molecules involved in DNA replication. ...
DNA helicase DNA replication DNA-protein interaction nuclear magnetic resonance (NMR) protein-protein interaction DNA replication restart DnaB helicase PriC single-stranded DNA-binding protein Introduction Replication of circular chromosomes found in many bacteria is initiated by sequence-specific binding of ...
Processing of DNA in replication, repair and recombination pathways in cells of all organisms requires the participation of at least one major single-stranded DNA (ssDNA)-binding protein. This protein protects ssDNA from nucleolytic damage, prevents hairpin formation and blocks DNA reannealing until ...

Replication occurs in both somatic and germ cells and requires the teamwork of multiple enzymes. These enzymes include: DNA polymerase: Synthesizes (polymerizes) a new strand of DNA DNA primase: Makes RNA primers which are needed for DNA polymerase to synthesize new DNA Topoisomerase: Unwinds ...

In priming, an enzyme called primase places a short sequence of RNA nucleotides into position at the origin of replication. This sequence is complementary to the 3 end of the single-stranded portion of the template at that point. DNA polymerase then adds nucleotides to the RNA's 3 OH, ...
DNA Replication: DNA replication is the process of making two copies of DNA from one parent strand. The process is complex, especially in eukaryotes that store their DNA in the nucleus. Many enzymes are involved in DNA replication, such as DNA polymerase, primase, helicase, topoisomerase and mo...
