Correct Answer - Option 1 : Bt. Brinjal

The correct answer is Bt. Brinjal.

  • Bacterial genes are functional units of DNA that have their effects through a diffusible product. The final product may be an RNA molecule, or the RNA intermediate may be translated into protein, which then exerts the effect.
  • The effect of the gene is manifested in a phenotype, an observable property of the organism.

  • Bt.Brinjal is Bacillus Thuringiensis Brinjal. It is a genetically modified Brinjal.
  • It is developed to give resistance to insects called lepidopteron. It is a very dangerous pest of Brinjal.
  • The resistant gene is taken from the soil bacterium called Bacillus Thuringiensis.
  • The gene for Cry 1 Ac is taken and inserted into the cultivars by the agrobacterium mediated gene transfer method.
