|
|
|
Because the bacteria were diabetic
|
|
|
Because bacteria have simple DNA that is easier to manipulate, making it easy to produce insulin in a lab
|
|
|
Because bacteria’s complex DNA was perfect for insulin production
|
|
|
Because insulin has no use outside of a lab setting
|
Detailed explanation-1: -Many diabetics, therefore, must inject insulin into their bodies daily. Prior to the 1980s, insulin for diabetics came from pigs and was very expensive. To create insulin inexpensively, the gene that produces human insulin was added to the genes in a normal E. coli bacteria.
Detailed explanation-2: -Answer and Explanation: Scientists used recombinant DNA technology to engineer bacteria to produce insulin because it was much more efficient than other methods, such as harvesting it from the pancreases of cows. Insulin then became more easily and widely available.
Detailed explanation-3: –Scientists have inserted genes for insulin and other proteins into bacteria and yeast cells so that the cells synthesize these proteins in vast quantities.-Genetically engineered proteins are safer and less expensive than proteins isolated from donated blood or from animals.
