Question

With reference to agriculture in India, how can the on technique of 'genome sequencing', often seen in the news, be used in the immediate future?

1. Genome sequencing can be used to identify genetic markers for disease resistance and drought tolerance in various crop plants.

2. This technique helps in reducing the time required to develop new varieties of crop plants. 

3. It can be used to decipher the host-pathogen relationships in crops.

Select the correct answer using the code given below:

(a) 1 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Answer 1

Correct option is (d) 1, 2 and 3

It explains the benefits of human genome sequencing that- "It is the sequence of bases in DNA that determines the genetic information of a given organism. So, learning about the DNA sequences can lead to an understanding of their natural capabilities that can be applied toward solving challenges in health care, agriculture, energy production, environmental remediation." So on that logic, statement 1 and 3 should be possible, and if 1 and 3 are possible then statement 2 ought to be possible as well! So answer (d) all three statements are correct.
