DNA replication is a cellular process that is replication for the duplication of DNA content in cells. A number of enzymes and proteins are involved in the replication. During replication, each DNA strand of the double-stranded DNA (dsDNA) serves as the template strand for the synthesis of ...
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?
Cyclin-dependent kinases (CDKs) meticulously regulate the DNA replication process by phosphorylating various replication factors, enabling their entry into the S phase, and facilitating DNA synthesis (6). A failure in this regulatory system can have severe consequences, including the onset of diseases...

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, ...

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 ...
DNA polymerase catalyzes the process of DNA replication and repair during cellular respiration. Learn about DNA polymerase function, structure, and...
