Chromosomal DNA sequences from Ustilago maydis promote autonomous replication of plasmids in Saccharomyces cerevisiae
1National Institute for Medical Research, Mill Hill, NW7 1AA, London, UK.
Abstract:
U. maydis chromosomal DNA sequences which promote the autonomous replication of plasmid YIp5 in S. cerevisiae YNN27 have been isolated and three of them characterised in some detail. Their properties are idential to yeast ars sequences in that plasmids containing them are maintained extrachromosomally as circular double-stranded DNA molecules, are mitotically unstable in yeast transformants and transform yeast at high frequencies. There is no sequence homology between the three U. maydis sequences and they are not reiterated in the U. maydis genome.

Chromosome Structure
The centromere is a DNA sequence that links sister chromatids. This is also where kinetochores, protein complexes to which spindle microtubules attach, are constructed after the chromosome is replicated. The kinetochores allow the spindle microtubules to move the chromosomes within the cell during cell division.
