DNA Ligase is an enzyme that joins DNA fragments together by catalyzing the formation of phosphodiester bonds. This function is analogous to stitching or gluing pieces together, hence they are often referred to as "molecular stitchers" or "molecular glue". Restriction Endonucleases are enzymes that cut DNA at specific recognition nucleotide sequences. They are often referred to as "molecular scissors". DNA Polymerase is an enzyme that synthesizes new DNA strands by adding nucleotides.
Which of the following pairs is correctly matched?

- Recombinant DNA technology (Genetic Engineering) allows genes to be transferred 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.
- Transfer across different species of plants: Yes, this is common in developing Genetically Modified (GM) crops, for example, transferring herbicide resistance genes between plant species or varieties. 2. From animals to plants: Yes, while perhaps not as common as plant-to-plant or microorganism-to- plant transfers for agricultural purposes, it is technically possible to transfer genes from animals to plants using genetic engineering techniques. This has been explored in research for various purposes. 3. From microorganisms to higher organisms: Yes, this is a very common application. For instance, transferring genes from bacteria (like the Bt gene) to plants for pest resistance (e.g., Bt cotton), or inserting genes from humans into bacteria or yeast for the production of therapeutic proteins like insulin. 159.
