Detailed explanation-1: -Recombinant molecules enter living cells in a process called transformation. Usually, only a single recombinant molecule will enter any individual bacterial cell. Once inside, the recombinant DNA molecule replicates like any other plasmid DNA molecule, and many copies are subsequently produced.
Detailed explanation-2: -For a variety of reasons, bacteria are used in recombinant technology. They have plasmid DNA, which is extrachromosomal DNA that can multiply on its own. They are simpler to control and quickly duplicate in a medium. It is simple to screen, pick, and transfer transformants to the target cells.
Detailed explanation-3: -Recombinant DNA is a technology scientists developed that made it possible to insert a human gene into the genetic material of a common bacterium. This “recombinant” micro-organism could now produce the protein encoded by the human gene.
Detailed explanation-4: -Recombinant DNA technology is an extremely important research tool in biology. It allows scientists to manipulate DNA fragments in order to study them in the lab. It involves using a variety of laboratory methods to put a piece of DNA into a bacterial or yeast cell.
Detailed explanation-5: -Using recombinant DNA technology, scientists are able to create new DNA sequences that would not naturally exist under normal circumstances and environmental conditions. The resulting recombinant DNA is put into a host cell, where it is expressed into a new protein, which is the so-called recombinant protein.
