Construction of artificial chromosomes in yeast.
Fifty-five-kilobase long artificial chromosomes containing cloned genes, replicators, centromeres and telomeres have been constructed in yeast. These molecules have many of the properties of natural yeast chromosomes. Centromere function is impaired on short (less than 20 kilobases) artificial chromosomes.
