The videos from class:
This video talks about how a bacterial plasmid is cut by restriction enzymes, allowing a gene to be inserted into the bacterial DNA. The bacterium then produces the proteins encoded in the DNA of the inserted gene.
An animation showing the DNA being cut by the restriction enzyme EcoR1 - look out for the enzyme searching the DNA for a specific sequence.
In this video, the nucleus of an egg is removed, and is replaced by the nucleus of a body cell (such as a skin or muscle cell). Using the nucleus, the egg then divides and develops into an embryo using the instructions encoded in the DNA. The cells in this egg are exact clones of the skin cell used to create it:
