Artificial chromosomes are laboratory constructs that contain DNA sequences and that perform the critical functions of natural chromosomes. They are used to introduce and control new DNA in a cell, to study how chromosomes function, and to map genes in...

Bacterial artificial chromosomes (BACs) involve a cloning system that is derived from a particular plasmid found in the bacterium Escherichia coli. The use of the BAC allows large pieces of deoxyribonucleic acid (DNA) from bacterial or nonbacterial...

Bacterial artificial chromosomes (BACs) are large F-based plasmid vectors that can accommodate large inserts of DNA. The inserts can be up to 350,000 bases in length. Since their introduction in 1992, the BAC has served an important role in human and...

A bacterial artificial chromosome (BAC) is a DNA construct, based on a fertility plasmid (or F-plasmid), used for transforming and cloning in bacteria, usually E. coli. F-plasmids play a crucial role because they contain partition genes that promote the...

Comparative Sequence Analysis of Colinear Barley and Rice Bacterial Artificial Chromosomes1 Colinearity of a large region from barley (Hordeum vulgare) chromosome 5H and rice (Oryza sativa) chromosome 3 has been demonstrated by mapping of several common restriction fragment-length polymorphism clones on both regions....

ABSTRACT Twenty bacterial artificial chromosome (BAC) clones that could produce bright signals and no or very low fluorescence in situ hybridization (FISH) background were identified from Gossypium arboreum cv. JLZM, and G. hirsutum accession (acc.) TM-1 and 0-613-2R. Combining with 45S and 5S...
