Write notes on : Genetically modified organism.

Explanation

Plants, fungi, bacteria and animals whose DNA has been manipulated to possess and express a foreign DNA, are called, genetically modified organisms or transgenic organisms.
GMOs have wide ranging application in agriculatural and animal husbandry, medicine and healthcare management and environmental monitoring and management.
Advantage of GMOs are as follows:
Genetic modification has made the crops more tolerant to abiotic stresses like cold, heat, drought, etc.
It has reduced the dependence of crops on chemical pesticides as they are made pest resistant.
Post harvest losses are much reduced.
These plants have increased efficiency of mineral usage and hence, the early exhaustion of soil fertility is prevented.
Food produced from GM crops have enhanced nutritional value.
