Detailed explanation-1: -Expert-Verified Answer. Human insulin made by bacteria is injected into humans correctly describes a way that bacteria are used in biotechnology. Explanation: Human body do make insulin from the beta cells of islet of Langerhans.
Detailed explanation-2: -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.
Detailed explanation-3: -Q. Which statement correctly describes a way that bacteria are used in biotechnology? Bacteria make human cells that make insulin.
Detailed explanation-4: -Nowadays, recombinant human insulin is mainly produced either in E. coli or Saccharomyces cerevisiae. Using E. coli expression system, the insulin precursors (IP) are produced as inclusion bodies and fully functional polypeptides are obtained finally by solubilization and refolding procedures [16].
Detailed explanation-5: -The genetic engineering process The gene for human insulin is inserted into the gap in the plasmid. This plasmid is now genetically modified. The genetically modified plasmid is introduced into a new bacteria or yeast cell. This cell then divides rapidly and starts making insulin.
