A technique for separating molecules through their migration on a support medium while under the influence of an electrical potential.
Term
Epithelial Cells
Definition
The outer layer of skin cells.
Term
Human Genome

Term
Replication
Definition
The synthesis of new DNA from existing DNA.
Term
Restriction Enzyme

A region of a DNA molecule that contains short segments of three to seven repeating base pairs.
Term
Substrate Control
Definition
An unstained object adjacent to an area on which biological material has been deposited.
Term
Tandem Repeat
Definition
A region of a chromosome that contains multiple copies of a core DNA sequence that are arranged in a repeating fashion.
Term
Touch DNA
Definition
DNA from skin cells transferred onto the surface of an object by simple contact.
