Examples
of
Yeast
Plasmid
Vectors - The possible examples of the yeast plasmid vectors are
(i) YIp or yeast integrative plasmids, which allow transformation by crossing over and have no replication origin
(ii) YEp or yeast episomal plasmids, which carry 2 micron DNA sequence including the origin of replication and rep genes
(iii)YRp or yeast replicating plasmids, which carry autonomously replicating sequence; this sequence is very common with many yeast genes so that stable transformation can be achieved by crossing over
