UPSC General Studies Solved Paper - General Studies-2017

  • question_answer
    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 relationship in crops.
    Select the correct answer using the code given below:

    A)  Only 1             

    B)  2 and 3    

    C)  1 and 3

    D)         1, 2 and 3

    Correct Answer: D

    Solution :

    Exp. [d] Agrigenomics is a branch of genome sequencing study, consist of sequencing and genotyping technologies touch many steps of the Agrigenomics pipeline. It also involves study of host pathogen relationship in crops for example, Genes Related to Insecticide Resistance in Bactrocera dorsalis. Decoding genome sequence of wheat can help in developing climate smart wheat. A complete and accurate description of the wheat genome will allow for the quick identification of critical genes that code for everything from drought resistance to stress resistance.
