Question

Why is insulin produced by genetically engineered E. coli cells superior to insulin obtained from animal sources? 0 a. Animal insulin is more difficult to purify than recombinantly produced insulin. O b. Recombinantly produced insulin has a much higher activity level. O c Recombinantly produced insulin contains human rather than animal sequences, reducing the chances ofan allergic response. O d. Animal insulin has a shorter life span than insulin produced using recombinant DNA techniques O e. Recombinantly produced insulin is easier to obtain than insulin from animals.

Explanation / Answer

The correct answers are option A, C & E

The insulin gene present in E.coli is belongs to human, so no genetic consequences occur.

Purification of insulin from E.coli is easier than animal. Animal insulin may have contaminated during extraction and purification.
