Semi-conservative replication
• Now two identical molecules
of DNA exist where there
was one before
• Each molecule contains one
strand of the original DNA
When does DNA replication occur?
• Every time a cell divides--so that each cell will have all the instructions needed to produce proteins to do the cellular work
Cells divide to:
• Reproduce!
In asexual reproduction of single celled organisms, a new organism is created by simply dividing in two
So the organism must replicate its DNA and its organelles as well in order to end up with two exactly identical cells
