Frequently Asked Questions

How does DNA replication occur?

DNA has to be accurately copied during cell division to propagate the information to daughter cells DNA replication occurs through a semiconservative mechanism, because each new molecule is made up of one old strand and one new strand. DNA helicase separates the strands to allow them to be copied. DNA polymerase synthesises new DNA from each strand

What enzymes are involved in DNA replication?

During DNA replication, one new strand (the leading strand) is made as a continuous piece. The other (the lagging strand) is made in small pieces. DNA replication requires other enzymes in addition to DNA polymerase, including DNA primase, DNA helicase, DNA ligase, and topoisomerase.

What are the 3 models of DNA replication?

The 3 models that were introduced to explain the process of DNA replication are conservative replication, semi-conservative replication, and dispersive replication. Which enzymes are involved in the process of DNA replication?

Is DNA replication semiconservative?

DNA replication is semiconservative. The original strands of DNA act as a template for the synthesis of new strands of DNA. So each new DNA molecule is made up of one parent strand (see next point) from the original DNA molecule, and one new, daughter strand.
