A unicellular form of fungi. Because it is so widely used in studies of Eukaryotic genetics, the term yeast often refers to S. cerevisiae when a specific genus is not indicated. A cloning vector which contains sequences from a yeast chromosome required for DNA replication and segregration. A yeast vector carrying the 2 m circle origin of replication.
Yeast extract A water soluble preparation extracted from common yeast.
Yeast extract is rich in amino acids, peptides, B vitamins, and trace elements. Commonly used in rich media. A yeast vector that relies on integration into the host chromosome for replication. A yeast vector that carries a chromosomal origin of replication. An approach developed by Stan Fields and colleagues in 1989 to identify protein-protein interactions in vivo.
