Today In Class we first talked over electrophoresis, plasmids and also Restriction Sights.

- Gel Electrophoresis is used to separate DNA fragments.

- Shorter fragments move faster and more farther away from the starting point compared to the longer fragments.

- Gel Electrophoresis is used often in crime scenes because it compares the DNA from the crime scene to a certain prospect.

Plasmid: is a small circular DNA which is located in the cytoplasm of a bacteria.

(Here is a picture of Plasmid DNA formation)

This picture shows how bacteria can be transformed using recombinant plasmids.

Restriction Sight: It is the location where the restriction enzyme can be cut at.

Recombinant DNA molecules are made up of DNA from a various group of sources. The restriction enzymes cut the DNA at certain spots (Restriction Sight), and then produces "sticky ends". When two DNA molecules are cut with the same restriction enzyme, then the sticky ends will bond together (in the fragment) of the DNA which have sides which are complementary.
