- The process of DNA replication
- involves several steps. First, the hydrogen bonds
- between the nitrogenous bases rupture and the two
- nucleotide chains begin to uncoil from the midpoint
- of the double helix. Second, DNA polymerase, an
- enzyme, brings deoxyribonucleotides that are
- free-floating in the nulceoplasm to each of the
- chains. In this way, each old chain acts as a
- template for the synthesis of the two new chains,
- and, consequently, two exact copies of the original
- double-stranded DNA molecule are produced, each
- containing one old and one new strand.
