- Chromasome must make copies of themselves for cell division.
- The copying of DNA is called replication and takes place during interphase.
- During replication, the hydrogen bonds holding the complimentary base pairs together break and the two DNA strands separate.
- As the template DNA unwinds/separates, DNA polymerase catalyses the addition of free complimentary nucleotides to free bases.
- This results in two DNA molecules, each made up of one new chain and one chain conserved from…
