Definitions:

Plasmids

Small, circular, double-stranded DNA molecules that are separate from a cell's chromosomal DNA and can replicate independently, often used in genetic engineering.

Recombinant Organisms

Organisms that have been genetically engineered by inserting DNA from a different organism to gain desired traits.

Sticky Ends

are the single-stranded overhangs left after DNA is cut by certain restriction enzymes, which can bond with complementary sticky ends of other DNA fragments.

Restriction Enzymes

Restriction enzymes are proteins that cut DNA at specific nucleotide sequences, used in molecular biology for DNA manipulation and analysis.
