What is leading strand in DNA replication? What controls the process of DNA replication? Define DNA replication What is the role of DNA helicase during DNA replication? What type of replication is DNA replication? How does DNA replication work?
At the beginning of replication, DNA is unzipped by helicase (yellow). Then primase (red) creates the first few base pairs that DNA polymerase (blue) will recognize, before it begins replication.DNA replicationScitable

We have used cells from ICF patients (Immunodeficiency Centro- meric instability and Facial anomalies, OMIM ID: 242860) to inves- tigate how a DNA methylation defect affects DNA replication in human cells. ICF syndrome is a rare autosomal recessive disorder that is characterized by immunodeficiency...
The role of simian virus 40 (SV40) large tumor antigen (T antigen) as a DNA helicase at the replication fork was studied. We found that a T-antigen hexamer complex acts during the unidirectional unwinding of appropriate DNA substrates and is localized directly in the center of the fork, con...
Why does DNA synthesis require an RNA primer? Why is there no helicase in a PCR? Why are nucleotide bases hydrophobic? Why is adenine used for energy more than the other nucleotides? What sugar distinguishes RNA from DNA? Why is DNA replication important?
How does the structure of DNA result in accurate replication? How can DNA replication be modeled? How do cells help ensure that DNA replication is accurate? How does DNA replication work? How is DNA replication used in biotechnology? How is base pairing involved in DNA replication?
