DNA notes 2015 - OG
... Fingerprinting takes the DNA out of a cell and separates it. This will allow investigators to distinguish body cells of different individuals (since they are unlikely to have the same DNA) Cloning – take the DNA out of one of your cells then take the DNA out of a zygote (fertilized egg). Put the DNA ...
