Detailed explanation-1: -What is an advantage of using transgenic bacteria to produce human proteins? Transgenic bacteria can produce human proteins in large amounts because bacteria reproduce rapidly.
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.
Detailed explanation-3: -GM yeasts are an important source of enzymes used in food production (e.g., cheese-making) and in improving the quality of beer and wine. GM bacteria are used in the production of enzymes such as milk-clotting enzymes for cheese production and food/feed additives such as aspartame and l-lysine.
Detailed explanation-4: -Using restriction enzymes, scientists can cut and paste together DNA from different species. For example, by cutting and pasting the gene for human insulin into bacteria, we can use the bacteria as biofactories to produce insulin for diabetic patients.
