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 complimentary strand. Together the template strand and the complimentary 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.
