WebYeast artificial chromosomes (YACs) are genetically engineered chromosomes derived from the DNA of the yeast, Saccharomyces cerevisiae [1], 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. In nature, yeast cells are found primarily on ripe fruits such as grapes (before maturation, grapes are almost free of yeasts). S. cerevisiae can also be found year-round in the bark of oak trees. Since S. cerevisiae is not airborne, it requires a vector to move. Queens of social wasps overwintering as adults (Vespa crabro and Polistes spp.…
