These mechanisms, in conjunction with recombination process

The principal approach that has been developed to circumvent this difficulty is to effect a physical separation of the gene of interest from the chromosome by cloning in a bacterial plasmid. The problem is then resolved by utilization of a procedure for the selective visualization

In the first stage of the process of transcription, RNA polymerase recognizes and binds to a specific sequence on the DNA, a promoter, just upstream of the point at which transcri
