The bioengineered food products are those food products, which are modified by the alteration in their genetic material. There alteration in the genetic material is done by changing and incorporating the gene of interest in the DNA of the organism. Sometimes, the gene of interest are derived from the genome of the other organisms.
The use of the chemical pesticides escalated the green revolution, at that time the genetically modified food product were not so developed.
Hence, the correct answer is c. They were developed during the Green Revolution.
The answer is: b.<span>They have been genetically modified.</span> >Genetically modified foods<span> or </span>GM foods are <span> </span>genetically engineered foods. They <span>are foods produced from </span>organisms<span> that have had changes introduced into their </span>DNA<span> using the methods of </span>genetic engineering. >Bioengineered foods<span> are foods that have had a gene from a different species of plant or other organism introduced to produce desired characteristics or traits.</span>
