Recombination DNA technology (Genetic Engineering) allows genes to be transferred:1. Across different species of plants2. From animals to plants3. From microorganisms to higher organismsSelect the correct answer using the codes given below.
✓ Correct answer: d) 1, 2 and 3 UPSC GS Paper-I PYQs 534
ExplanationRecombinant DNA technology entails changing genetic material outside of an organism to produce living organisms or their products with improved and desired traits.Using the appropriate vectors, this approach entails inserting DNA fragments from a number of sources that have the desired gene sequence.Manipulation in an organism’s genome is carried out either through the introduction of one or several new genes and regulatory elements or by decreasing or blocking the expression of endogenous genes through recombining genes and elements.Recombinant DNA technology, also known as genetic engineering, enables the transfer of genes across different species, including: Across different species of plants: Genes can be transferred between various plant species to introduce desirable traits.From animals to plants: Animal genes can be introduced into plants to confer new characteristics.From microorganisms to higher organisms: Microbial genes can be inserted into higher organisms, such as plants or animals, to impart beneficial properties.17
