Genome sequencing

45) 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:

(a) 1 only

(b) 2 and 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Solution: (d) 1, 2 and 3

Genome sequencing is figuring out the order of DNA nucleotides, or bases, in a genome—the order of As, Cs, Gs, and Ts that make up an organism’s DNA.

Currently available newborn screening (genome) for childhood diseases allows detection of rare disorders that can be prevented or better treated by early detection and intervention.

If the gene potential can be identified by screening and sequencing, it will help in better genetic engineering.
