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.  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 [1].


The term "semi-conservative" refers to the fact that each of daughter double helix contains one conserved strand from the parent DNA, as well as one newly synthesised strand.
