Question

Which of the following statement/s is/are an example of genetic engineering? I. Inserting a gene for human insulin production into bacteria. II. Selective breeding to produce cattle with high milk yields. III. Using methods like crop rotation with leguminous plants to increase the fertility of the soil. IV. Vegetative propagation and grafting are practised to ensure higher yield., I, II and IV, II and III, I and III, Only I

MARKS App · Accepted Answer

Techniques to alter the chemistry of genetic material (DNA and RNA), to introduce these into host organisms and thus change the phenotype of the host organism come under genetic engineering. Statement I is only one where the gene is been manipulated artificially to get the desired effect. Selective breeding can be considered as gene manipulation but there is no control on the outcome but chance.
