Question

Production of insulin by recombinant dna technology

Answer 1

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.
Scientists build the human insulin gene in the laboratory. Then they remove a loop of bacterial DNA known as a plasmid and insert the human insulin gene into the plasmidResearchers return the plasmid to the bacteria and put the “recombinant” bacteria in large fermentation tanks. There, the recombinant bacteria use the gene to begin producing human insulin. Scientists harvest the insulin from the bacteria and purify the substance for use as a medicine for people.
