Question

From which animals were insulin obtained in the early days?

(a) Insects

(b) Lizard and snakes

(c) Cats and dogs

(d) Cattle and pigs

This question was posed to me in an online interview.

My question is taken from Biotechnological Applications in Medicine: Genetically Engineered Insulin in chapter Biotechnology and its Applications of Biology – Class 12

Answer 1

Right option is (d) Cattle and pigs

For explanation I would say: In early days the insulin was obtained from the pancreas of cattle and pigs. Insulin obtained this way had many disadvantages. Nowadays insulin is obtained using recombinant DNA technology. For this microorganisms are used.
