1.	Use of certain chemicals and radiation to change the base sequences of genes of crop plants is termedA. Recombinant DNA technologyB. transgenic mechanismC. Mutation breedingD. gene therapy
Answer» Correct Answer - C it is possible to induce mutations artficially in crop plants through the use of chemicals or radiations (like gamma radiations ) , and then seleting and using those plants that have the sesirable character as a source in breeding , this process is called mutation breeding . Use of readiations is not involed in other options Recombinant DNA techology involes transfering of a desired engtic engineeing gene (trans gene) from an organism and incorating it to host oprganism by genetic engineering to produce a recombinant to gene therapy is performed mainly in humans , it involes replacing replacing a defertive gene with a normal one.
