Question
How is Biotechnology useful in the development of agriculture?
Solution
- Agricultural yield and crop variety can be improved by implementing biotechnological techniques for agriculture.
- Hybrid seeds are developed, in which two different crops are recombined.
- Genetically modified crops having desired characters are developed by incorporating a foreign gene into the genome of crops by biotechnological techniques.
- Genetic modification enables the development of high-yielding varieties with resistance to diseases, weeds, herbicides, cold, drought and soils with high alkalinity. e.g. Bt cotton, golden rice, etc.
- Bacteria like Rhizobium, Azotobacter, Nostoc, Anabaena and plants like Azolla can be used as biofertilizers to improve the abilities of nitrogen fixation and phosphate solubilization by plants.

Vaccination gives either permanent or temporary immunity against a specific pathogen or disease. Traditionally, vaccines were prepared with the help of pathogens. Completely or partially killed pathogens were used as vaccines. However, due to this, there were chances of contracting the disease in case of some persons. Hence, as an alternative, scientists tried to artificially produce vaccines with the help of biotechnology. For this purpose, scientists produced the antigen in the laboratory with the help of genes isolated from the pathogen and used it as a vaccine. Thus, safer vaccines are being produced. Work on production of edible vaccines is in progress and presently, potatoes are being produced with the help of biotechnology. These potatoes are called transgenic potatoes. These potatoes will act against bacteria like Vibrio cholerae, Escherichia coli. Consumption of these raw potatoes generates immunity against pathogens. For the production of such edible vaccines, antigens are produced by isolating the desired gene from human pathogens and injecting it into plants.
- How can people who have been vaccinated get infected?
- Why are vaccines produced with the help of biotechnology safer than conventional vaccines?
- How does the immune system respond to vaccination?
- What is the disadvantage of transgenic potatoes?
- Why is vaccination more beneficial than antibiotics?
