BAC and YAC
Commonly used vector for human genome sequencing are BAC (Bacterial Artificial Chromosome) and YAC BAC is a DNA construct, based on a functional fertility plasmid (Fplasuid) used for transforming and cloning in bacteria (e.coil) and YAC are genetically engineered chromosomes derived from the DNA of the yeast Saccharomyces cerevisiae, which is then ligated into a bacterial plasma.
