Clones are organisms that are exact genetic copies. Every single bit of their DNA is identical. Principle objective of this lecture is to present on What is Cloning. Clone refers to genetically identical cells originating from one cell. They take DNA from a cloned cell of another animal, and insert it into a zygote that had its DNA removed, and replace it with the cloned DNA. There are two ways to make an exact genetic copy of an organism in a lab: artificial embryo twinning and somatic cell nuclear transfer.
