An enzyme that cuts DNA into fragments (molecular scissors) at specific sites

The DNA in its tiny fragments after restriction enzymes 

The specific spot where restriction enzymes cut

Differences in DNA sequence on homologous chromosomes that can result in different patterns of restriction fragment lengths

Pairs of letters on the opposite sides of each other on the DNA ladder

The technique/procedure used to separate DNA fragments according to their size/charge

The size standard or a DNA ladder loaded into the first well of the gel. The fragments in the marker are of known length to measure size of the fragments in the samples. Also used as a control.

An individual's DNA characteristics that provides the key info about human identity.

Process by which DNA copies itself

Straight fragment ends of a DNA molecule that preserve both base pairs resulting from cleavage by a restriction enzyme
