Question

Use of certain chemicals and radiation to change the base sequence of genes of crop plants is termed as ?

• A. Recombinant DNA technology
• B. Transgenic mechanism
• C. Mutation breeding
• D. Gene therapy

Answer 1

The correct option is C Mutation breeding

• Mutation breeding is the process of exposing seeds to certain chemicals and radiation in order to generate mutants with desirable traits to bred with other cultivators. This will change the base sequence of genes of crop plants. In mung bean, resistance to yellow mosaic virus and powdery mildew were induced by mutations.
  
• Recombinant DNA technology is the process of joining DNA molecules together from 2 different species that are inserted into a host organism to produce new genetic recombinations.
• Transgenic mechanism is the mechanism of random integration of foreign DNA in transgenic animals.
• Gene therapy is a therapeutic process of delivery of nucleic acid into a patient's cell as a drug to treat a disease.

So, the correct option is 'Option C' .
