Detailed explanation-1: -molecule is called a DNA vector (carrier). The most commonly used vectors are plasmids (circular DNA molecules that originated from bacteria), viruses, and yeast cells.
Detailed explanation-2: -Yeast vectors can be grouped into five general classes, based on their mode of replication in yeast: YIp, YRp, YCp, YEp, and YLp plasmids. With the exception of the YLp plasmids (yeast linear plasmids), all of these plasmids can be maintained in E. coli as well as in S.
Detailed explanation-3: -The linear DNA plasmids (pGKl1 and pGKl2) from Kluyveromyces lactis are the first case of yeast plasmids associated with biological function (killer phenotype). This plasmid system would be ideal as a model to study the structure and function of eukaryotic linear chromosomes.
