A Correct answer
Explanation

Biotechnology is being used to address problems in all areas of agricultural production and processing. This includes plant breeding to raise and stabilize yields; to improve resistance to pests, diseases and abiotic stresses such as drought and cold; and to enhance the nutritional content of foods.

Genetic modification (GM) has been used to

  1. Create tailor made plants

  2. Supply alternative resources to industries

  3. Enhanced nutritional value of food

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Genetic modification by the introduction of the recombinant DNA has resulted in the creation of tailor-made plants that can be pest resistant, drought resistant, herbicide resistant, etc. It has supplied alternative to dairy farm industries by modifying plants and animals. It has also resulted in the creation of biofortified crops that have enhanced nutritional values of food.

Hence, the correct answer is 'All of the above'

Multiple-choice Question

Find out the correct sentence:

  1. Hybridisation means crossing between genetically dissimilar plants

  2. Cross between two varieties is called as interspecific hybridisation

  3. Introducing genes of desired character into a plant gives genetically modified crop

  4. Cross between plants of two species is called intervarietal hybridisation
Reveal answer Fill a bubble to check yourself
A,C Correct answer
Explanation

Hybridisation is the interbreeding between two genetically different organisms from the same or different species. When such interbreeding is between different species it is known as interspecific hybridisation. Genetically modified crops are those that are genetically engineered by introducing the genes of the desired trait (character) into the plants. When the cross is between two different varieties of the same species then it is known as intervarietal hybridisation. So, the correct options are 'Hybridisation means crossing between genetically dissimilar plants and Introducing genes of the desired character into a plant gives genetically modified crop'.
