2. With reference to agriculture in India, how can the technique of ‘genome sequencing’, often seen in the news, be used in the immediate future? [UPSC (Pre)—2017] 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

3. In the context of the developments in Bioinformatics, the term transcriptome, sometimes seen in the news, refers to [UPSC (Pre)—2016] (a) A range of enzymes used in genome editing (b) The full range of mRNA molecules expressed by an organism (c) The description of the mechanism of gene expression (d) A mechanism of genetic mutations taking place in cell

5. Which of the following statements is/are correct regarding vegetative propagation of plants? [UPSC (Pre) —2014]

1. Vegetative propagation produces clonal population. 2. Vegetative propagation helps in eliminating the virus. 3. Vegetative propagation can be practiced most of the year. 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



6. Consider the following techniques/phenomena: [UPSC (Pre)—2014] 1. Budding and grafting in fruit plants 2. Cytoplasmic male sterility3. Gene Silencing

Which of the above is/are used to create transgenic crops? (a) 1 only (c) 1 and 3 (b) 2 and3 (d) None


7. Recombinant DNA technology (Genetic Engineering) allows genes to be transferred [UPSC (Pre)—2013]

1. across different species of plants 2. from animals to plants 3. from microorganisms to higher organisms Select the correct answer using the codes given below. (a) 1 only (c) 1and 3only (b) 2 and 3 only (d) 1,2 and 3


8. Mycorrhizal biotechnology has been used in rehabilitating degraded sites because mycorrhiza enables the plants to [UPSC (Pre)—2013] 1. Resist drought and increase absorptive area 2. Tolerate extremes of pH 3. Resist disease infestation Select the correct answer using the codes given below. (a) 1 only (c) 1and3only (b) 2 and 3 only (d) 1,2and3

10. With reference to ‘stem cells’, frequently in the news, which of the following statements is/are correct? [UPSC (Pre)—2012] 1. Stem cells can be derived from mammals only. 2. Stem cells can be used for screening new drugs. 3. Stem cells can be used for medical therapies. Select the correct answer using the codes given below: (a) 1 and 2 only (b) 2 and 3 only (c) 3 only (d) 1, 2 and 3


11. What are the reasons for the people’s resistance to the introduction of Bt brinjal in India? [UPSC (Pre)—2012] 1. Bt brinjal has been created by inserting a gene from a soil fungus into its genome. 2. The seeds of Bt brinjal are terminator seeds and therefore, the farmers have to buy the seeds before every season from the seed companies. 3. There is an apprehension that the consumption of Bt brinjal may have adverse impact on health. 4. There is some concern that the introduction of Bt brinjal may have adverse effect on the biodiversity.
