The DNA double helix is split into individual strands by DNA Helicase, read by DNA Polymerase and the appropriate monomers (nucleotides) are attached to the original strand.
Explanation:
As they're being split, the individual DNA strands are read and copied in opposite directions. Nucleotides from the surrounding cellular environment are attached to the original where appropriate. Where there is an adenine on the original, and thymine is paired with it and linked with the growing strand (visa versa). Same with cytosine and guanine.
DNA ligase is an enzyme that ensures that there are no gaps/holes between nucleotides (monomers). What results is two copies of identical DNA each containing one half from the original DNA.
