DNA replication is a biological process which occurs in all living organisms, where a double stranded DNA molecule is copied to make 2 identical molecules (DNA Replication - wiki). The DNA copies would have one of the strands from the original DNA, and a one new one. Because of this, this process is a "semi-conservative" replication (DNA Replication Definition - Medical.)

These are the steps illustrating how DNA replicates:

(DNA Replication Process) || (Pickering) || (Pickering) ||
 * Step || What happens || Visual ||
 * 1 || The DNA is unwound and the two strands of DNA are seperated by a type of enzyme called helicase (DNA Replication Process) || [[image:Captgfkjmnrure.PNG width="250" height="186"]]
 * 2 || Proteins are released to keep the two DNA strands from binding together again (DNA Replication Process). || [[image:g10biodna-c/2.PNG width="252" height="176"]] (DNA Replication Process) ||
 * 3 || The two single DNA strands are used as a template for the complementary strands to be produced. The order of the nucleutides are determined by the base rule where A and T are together, and C and G are always together (DNA Replication Grade) || [[image:22344.PNG]]
 * 4 || The nucleuotides bound together. This completes the replication process, and produces two DNA molecules which are identical (DNA Replication Grade) || [[image:3.PNG width="167" height="160"]]
