DNA Copies

Replicas of DNA molecules that occur during cell division or as a result of molecular cloning techniques.

Restriction Enzymes

Proteins used in molecular biology that cut DNA at specific sequences, important for genetic engineering and recombinant DNA technologies.

Sticky Ends

Short, single-stranded overhangs produced by the cutting action of certain restriction enzymes on DNA, which can readily form hydrogen bonds with complementary sticky ends.
