|
The bacteria have been grown on a petri dish containing insulin.
|
|
|
The bacteria have been genetically engineered to contain the DNA needed to produce insulin.
|
|
|
The bacteria have been exposed to radioactivity to create mutant strains capable of producing insulin.
|
|
|
The bacteria have been grown on a petri dish containing sugar; the bacteria produce insulin in response to the sugar.
|
Detailed explanation-1: -This process is called recombinant technology. The bacterial DNA now contains the human insulin gene and is inserted into a bacteria. When the bacterial cells reproduce, the human insulin gene is also reproduced in the cells and produces protein by transcription and translation process.
Detailed explanation-2: -Bacteria can produce Human insulin in Recombinant DNA Technology because the genetic code for insulin is universal. Insulin is used to treat diabetes.
Detailed explanation-3: -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.
Detailed explanation-4: -Nowadays, recombinant human insulin is mainly produced either in E. coli or Saccharomyces cerevisiae.
