How are partial diploid E. coli constructs made?
What will be an ideal response?
The partial diploids are a special strain of bacteria that contain an engineered plasmid (the F factor) with a set of lac operon genes. This second set makes the cell "diploid" with respect to these genes. Partial diploids are strains of bacteria that contain an F' plasmid that bears a few chromosomal genes. These chromosomal genes in the F' plasmid do not necessarily have to be lac operon genes.
