CDS 01/2022: GK Previous Paper (Held On 10 April 2022)

In this technique, a gene from one organism is isolated and transferred to the cell of another organism.
This technique has applications only in plants.
Genes for insect resistance may spread from crop plants to wild plants.
To produce a transgenic animal the novel genes are inserted at a very early stage of development.

Answer 1

The correct answer is option 2.

Key Points

GMO (Genetically Modified Organisms)
- Techniques to alter the chemistry of genetic material (DNA and RNA), to introduce these into host organisms and thus change the phenotype of the host organism.
- The techniques of genetic engineering include
  - the creation of recombinant DNA, use of gene cloning, gene transfer, overcome this limitation and allow us to isolate and introduce only one or a set of desirable genes without introducing undesirable genes into the target organism.
- In this technique, a gene from one organism is isolated and transferred to the cell of another organism. Hence statement 1 is correct.
- A genetically modified organism (GMO) is an animal, plant, or microbe whose DNA has been altered using genetic engineering techniques. Hence statement 2 is not correct.
- Genes for insect resistance may spread from crop plants to wild plants. Hence statement 3 is correct.
- Animals that have had their DNA manipulated to possess and express an extra (foreign) gene are known as transgenic animals.
- To produce a transgenic animal the novel genes are inserted at a very early stage of development. Hence statement 4 is correct.
