Q70.
With reference to agriculture in India, how can the 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:
Answer
D
Explanation
All the statements are correct. Genome sequencing is figuring out the order of DNA nucleotides, or bases, in a genome. Genome sequencing of wild varieties of plants can be used to identify disease resistance and drought tolerance genes and develop new varieties of crop plants in lesser time. Genome sequencing of crop plants can also be helpful in deciphering and understanding the host-pathogen relationship in crops.
