| 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? |
A) Only 1
B) 2 and 3
C) 1 and 3
D) None of these
Correct Answer: B
Solution :
Exp. [b] Transgenic crops are. formed as a result of introduction of transgene into the genome of plant through recombinant DNA technology. Budding or Grafting Method is an example of vegetative propagation in plants. Cytoplasmic Male Sterility is used in development of hybrids. Gene silencing is used in r-DNA technology at times to suppress the expression of unwanted genes in an organism.
