Bacterial artificial chromosome

From Academic Kids

A bacterial artificial chromosome (BAC) is a DNA construct, based on a fertility plasmid, used for transforming and cloning in bacteria, usually E. coli. Its usual insert size is 150 kbp, with a range from 100 to 300 kbp.

BACs are often used to sequence the genetic code of organisms in genome projects, for example the Human Genome Project. A short piece of the organism's DNA is amplified as an insert in BACs, and then sequenced. Finally, the sequenced parts are rearranged in silico, resulting in the genomic sequence of the organism.
