What is DNA Replication?

DNA replication is the process by which DNA makes a copy of itself during cell division.  The first step in DNA replication is to ‘unzip’ the double-helix structure of the DNA  This is carried out by an enzyme called helicase which breaks the hydrogen bonds holding the complementary bases of DNA together (A with T, C with G).  The separation of the...
