When a plasmid vector containing foreign DNA is taken up by the host E. coli , the α-complementation does not occur, therefore, a functional β-galactosidase enzyme is not produced. Cloning, the process of generating a genetically identical copy of a cell or an organism. Transfer of plasmid DNA into bacteria. CRISPR has several things in common with "gene cloning" (the molecular technique of using Restriction Enzymes to create rBGH - recombinant bovine growth hormone - insulin for diabetics, and other proteins.

Biotechnology, the use of biology to solve problems and make useful products. In the 1950s, a phenomenon known as “host controlled/induced variation of bacterial viruses” was reported, in which bacteriophages isolated from one E. coli strain showed a decrease in their ability to reproduce in a different strain, but regained the ability in subsequent infection cycles (1,2). Colony hybridization begins with culturing sparsely populated bacterial colonies on a nutrient agar plate. Molecular Cloning.
