The enzyme DNA helicase causes the two strands of DNA to separate.
1 of 5
STAGE 2
DNA helicase completes the separation of the strand. Free nucleotides that have been activated are attracted to their complementary bases.

STAGE 3
Once the activated nucleotides are lined up, they are joined by DNA polymerase, the free nucleotides continue to join to their bases.

STAGE 4
Finally all the nucleotides are joined to form two identical polynucleotide chains. Each new molecule of DNA is composed of one original straw ad one newly formed molecule - so it is semi - conservative replication.

STAGE 5
Process is then repeated again on another strand on DNA - this is happening constantly in your cells.
