YAC stands for yeast artificial chromosome, a vector (carrier) created and used in the laboratory to clone pieces of DNA. A YAC is constructed from the telomeric, centromeric, and replication origin sequences needed for replication in yeast cells. (The telomere is the end of the chromosome; the centromere is the chromosome region to which spindle f [..]

Yeast artificial chromosome. This is a method for cloning very large fragments of DNA. Genomic DNA in fragments of 200-500 kb are linked to sequences which allow them to propagate in yeast as a mini-chromosome (including telomeres, a centromere and an ARS - an autonomous replication sequence). This technique is used to clone large genes and interge [..]

Yeast artificial chromosome. A cloning vector that can accept very large genomic inserts; a chromosome introduced to yeast derived from such a vector and containing DNA from another organism.
