ARS: Autonomously replicating sequence. ARS is the origin of replication in yeast.
Artificial selection: Selective evolutionary pressure imposed by humans to obtain breeds with certain features (such as breeding cows, dogs, chicken).

However, most (25out of 30) of the Trypanosome BACs with 130 kb average inserts, transform yeast at high efficiency, indicating the presence of ARS elements in most of the genomic insert fragments.

Some origins are well characterized, such as the autonomously replicating sequences (ARS) of yeast while other eukaryotic origins, particularly those in metazoa, can be found in spans of thousands of base pairs.

Autonomous replication sequence (ARS)
A segment of a DNA molecule necessary for the initiation of its replication; generally a site recognized and bound by the proteins of the replication system.

Originating from a bacterial plasmid; a YAC contains additionally a yeast centromeric region (CEN); a yeast origin of DNA replication (ARS); and two telomere regions (TEL). YACs are capable of cloning very large pieces 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).
