Question

boyer and cohen constructed the first organism with combined dna from different species in 1973, which has since led to incorporating ____________ into 70% of processed foods.

○ genetically modified ingredients
○ toad genes
○ bacterium
○ dna

Explanation:

Boyer and Cohen's work in 1973 was a significant step in genetic engineering. Genetic engineering techniques have been widely used to create genetically modified organisms (GMOs). Genetically modified ingredients, which are derived from GMOs, are now commonly incorporated into processed foods. Toad genes are not typically used in such a widespread way in food. Bacterium is too general and not specific to the context of being incorporated into 70% of processed foods in the way described. DNA is too broad as a term compared to genetically modified ingredients which is a more specific and relevant term in the context of food processing and genetic engineering applications.

Answer:

genetically modified ingredients
