Polymorphism within the nuclear and 2 micron genomes of Saccharomyces cerevisiae.

Seven strains of bakers' yeast were obtained as a representative sample of the Spanish baking industry. The nuclear genome was monitored for polymorphism by transverse alternating field electrophoresis (TAFE) and restriction maps of 2 micron DNA were produced. All seven strains were uniquely different when evaluated by their total chromosomal lengths… CONTINUE READING
