Genetic modification involves making changes to the organism's DNA, which can include adding new DNA or altering/removing existing DNA.
Genetically modified (GM) crops contain modified genetic material due to : introduction of new DNA removal of existing DNA introduction of RNA introduction of new traits Select the correct answer using the code given below:

- Consider the following techniques/ phenomena: 1. Budding and grafting in fruit plants 2. Cytoplasmic male sterility 3. Gene silencing Which of the above is/are used to create transgenic crops?
- Budding and grafting in fruit plants: These are methods of asexual (vegetative) propagation used to combine traits from different plants or propagate desired varieties. They do not involve introducing foreign genes to create a transgenic organism. This is not used to create transgenic crops. 2. Cytoplasmic male sterility: While CMS itself is a biological phenomenon used in hybrid breeding, genetic engineering techniques can be used to introduce or restore male sterility genes (like the barnase/barstar system), thereby creating transgenic plants with engineered CMS. In this context, the concept is linked to the creation of transgenics for breeding purposes. 3. Gene silencing: Techniques like RNA interference (RNAi) are methods of gene silencing where the expression of a specific gene is inhibited.
