Frequently Asked Questions

What is the definition of replication in biology?

n. 1. a. The act or process of replicating something. b. Biology The process by which genetic material, a single-celled organism, or a virus reproduces or makes a copy of itself. c. In scientific research, the repetition of an experiment to confirm findings or to ensure accuracy. d. A copy or reproduction: a replication of a famous painting. 2.

What is an RNA primer used for?

An RNA primer is added to the leading strand at complimentary bases by primase. DNA polymerase III attaches to the primer. The sliding clamp stabilizes DNA polymerase III. DNA polymerase III moves down the leading strand towards the replication fork, adding bases to the new strand from the 5’ end to the 3’ end.

How does DNA replication occur?

DNA replication is a process that occurs during cellular division where two identical molecules of DNA are created from a single molecule of DNA. As a semiconservative process, a single molecule containing two strands of DNA in double helix formation is separated, where each strand serves as a template for the new DNA molecules.

What is the enzyme that causes bacterial replication?

The process begins when the helicase enzyme unwinds the double helix to expose two single DNA strands and create two replication forks. DNA replication takes place simultaneously at each fork. The mechanism of replication is identical at each fork. Remember that the proteins involved in replication are clustered together and anchored in the cell.
