Biotechnology and its Applications

Solution:

Earlier, insulin was extracted from the pancreas of slaughtered cattle and pigs, but some patients began to develop allergies. The injection of this insulin into patients occasionally produces sensitivity reaction and side effects. Hence, it was less efficient than the genetically engineered insulin.
