Isolation of a yeast centromere and construction of functional small circular chromosomes

Nature. 1980 Oct 9;287(5782):504-9. doi: 10.1038/287504a0.


The centromeric DNA (CEN3) from yeast chromosome III has been isolated on a 1.6 kilobase-pair segment of DNA located near the centromere-linked CDC10 locus of Saccharomyces cerevisiae. When present on a plasmid carrying a yeast chromosomal replicator, CEN3 enables that plasmid to function as a chromosome both mitotically and meiotically. Minichromosomes containing CEN3 are stable in mitosis and segregate as ordinary yeast chromosomes in the first and second meiotic divisions.
