Semi-conservative replication is the mechanism by which DNA replicates in cells. The parent strand splits in two and uses itself as a template to form a second complementary strand. The exposed bases on the single-stranded DNA complementary base pair to nucleotides. A (Adenine) pairs with T (Thymine) and C (Cytosine) pairs with G (Guanine). Together the template strand and the complementary strand bond together to form a new double strand of DNA. One parent double strand of DNA will thus become two daughter double strands of DNA.
The term "semi-conservative" refers to the fact that each of the daughter double helixes contains one conserved strand from the parent DNA, as well as one newly synthesised strand.
