Read the passage and answer the following question.

Rohan's grandfather is suffering from diabetes and is dependent on insulin for diabetes treatment. Human insulin is produced by the Beta cells of the islets of Langerhans of the pancreas gland.  Earlier it was obtained from animals and was costly but now it is cheaper and easily available. It is due to biotechnology.

Mammalian insulin is synthesised as a prohormone called proinsulin that contains an extra chain called

Biotechnology, based on rDNA technology, has immense applications in crop improvement. Although conventional plant breeding techniques have made considerable progress in the development of improved varieties, they have not been able to keep pace with the increasing demand for food, vegetables and fruits. Use of rDNA technology has successfully led to the development of a number of transgenic plants exhibiting resistance to pathogens, salt, cold, herbicide, etc. Animals that have had their DNA manipulated to possess and express an extra (foreign) gene are known as transgenic animals.

Salt tolerant transgenic variety has been developed for
