Yeast artificial chromosomes (YACs) are genetically engineered chromosomes derived from the DNA of the yeast, Saccharomyces cerevisiae, which is then ligated into a bacterial plasmid. By inserting large fragments of DNA, from 100–1000 kb, the inserted sequences can be cloned and physically mapped using a process called chromosome walking .
Delitto perfetto (Italian: [deˈlitto perˈfɛtto]) is a genetic technique for in vivo site-directed mutagenesis in yeast. This name is the Italian term for "perfect murder", and it refers to the ability of the technique to create desired genetic changes without leaving any foreign DNA in the genome.
Yeast genes are classified using gene symbols (such as Sch9) or systematic names. In the latter case the 16 chromosomes of yeast are represented by the letters A to P, then the gene is further classified by a sequence number on the left or right arm of the chromosome, and a letter showing which of the two DNA strands contains its coding sequence.
A total of 1,078 cassettes were built, each 1,080 base pairs long. These cassettes were designed in a way that the end of each DNA cassette overlapped by 80 base pairs. The whole assembled genome was transplanted in yeast cells and grown as yeast artificial chromosome. [36]
Artificial chromosome may refer to: Yeast artificial chromosome; Bacterial artificial chromosome; Human artificial chromosome; P1-derived artificial chromosome; Synthetic DNA of a base pair size comparable to a chromosome
Cloning is generally first performed using Escherichia coli, and cloning vectors in E. coli include plasmids, bacteriophages (such as phage λ), cosmids, and bacterial artificial chromosomes (BACs). Some DNA, however, cannot be stably maintained in E. coli , for example very large DNA fragments, and other organisms such as yeast may be used.
The goal of transformation-associated recombination (TAR) technology in synthetic genomics is to combine DNA contigs by means of homologous recombination performed by the yeast artificial chromosome (YAC). Of importance is the CEN element within the YAC vector, which corresponds to the yeast centromere.
