DNA REPLICATION

WHAT IS DNA?

DNA is a molecule that has a repeating chain of identical five-carbon sugars (polymers) linked together from head to tail. It is composed of four ring shaped organic bases (nucleotides) which are Adenine (A), Guanine (G), Cytosine (C) and Thymine (T). It has a double helix shape and contains the sugar component deoxyribose.

THE PROCESS OF DNA REPLICATION

How DNA replicates is quite a simple process. First, a DNA molecule is "unzipped". In other words, it splits into two strands of DNA at one end of the DNA molecule. This separation will cause a formation of a replication fork.
After the replication fork has been established the strands of DNA are ready for the next stage. On each strand is a sequence of nucleotides. These nucleotides act as a template for complementary nucleotides to bind. Hence, it is the site where the synthesis of a new complementary strand will be formed.
Because of the DNA "unzipping", there will be two......
