The second yeast species to have its genome sequenced was Schizosaccharomyces pombe, which was completed in 2002. [108] [109] It was the sixth eukaryotic genome sequenced and consists of 13.8 million base pairs. As of 2014, over 50 yeast species have had their genomes sequenced and published. [110]
Saccharomyces cerevisiae (/ ˌ s ɛr ə ˈ v ɪ s i. iː /) (brewer's yeast or baker's yeast) is a species of yeast (single-celled fungal microorganisms). The species has been instrumental in winemaking, baking, and brewing since ancient times. It is believed to have been originally isolated from the skin of grapes.
Yeast artificial chromosomes (YACs) are genetically engineered chromosomes derived from the DNA of the yeast, Saccharomyces cerevisiae, which is then ligated into a bacterial plasmid. By inserting large fragments of DNA, from 100–1000 kb, the inserted sequences can be cloned and physically mapped using a process called chromosome walking .
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
The mating of yeast, also known as yeast sexual reproduction, is a biological process that promotes genetic diversity and adaptation in yeast species. Yeast species, such as Saccharomyces cerevisiae (baker's yeast), are single-celled eukaryotes that can exist as either haploid cells, which contain a single set of chromosomes , or diploid cells ...
DNA was first sequenced in 1977. The first free-living organism to have its genome completely sequenced was the bacterium Haemophilus influenzae , in 1995. In 1996 Saccharomyces cerevisiae (baker's yeast) was the first eukaryote genome sequence to be released and in 1998 the first genome sequence for a multicellular eukaryote, Caenorhabditis ...

Fission yeast switches mating type by a replication-coupled recombination event, which takes place during S phase of the cell cycle. Fission yeast uses intrinsic asymmetry of the DNA replication process to switch the mating type; it was the first system where the direction of replication was shown to be required for the change of the cell type.
