Mostly the DNA structure is double stranded in both eukaryotes and prokaryotes. However, in some viruses DNA is single stranded. DNA is a double stranded molecule held together by weak bonds between base pairs of nucleotides. The four nucleotides in DNA contain the bases: adenine (A), guanine (G), cytosine (C), and thymine (T).

To understand the process of DNA replication, you much first be familiar with the structure of DNA. Resembling a twisted ladder, DNA is a double helix formed with nucleotides, a phosphate and sugar backbone, and nitrogenous bases. There are four bases, and each one will only bond with it’s complement. Adenine will only bond with Thymine, and Cytosine with only Guanine. The double helix is.

Knowledge of DNA’s structure helped scientists understand how DNA replicates. DNA replication is the process in which DNA is copied. It occurs during the synthesis (S) phase of the eukaryotic cell cycle. DNA replication begins when an enzyme, DNA helicase, breaks the bonds between complementary bases in DNA (see Figure below). This exposes the bases inside the molecule so they can be “read.
