Question

engineers can examine the dna of a plant and turn certain genes on or off and even add new genes from other dna strands. what is this process called?

a. genetic engineering

b. chemical differentiation

c. chemical engineering

d. dna alteration

Explanation:

To solve this, we analyze each option:

• Option A: Genetic engineering involves manipulating an organism's DNA (turning genes on/off, adding new genes from other DNA). This matches the described process.
• Option B: Chemical differentiation is not related to DNA manipulation of plants.
• Option C: Chemical engineering deals with chemical processes, not DNA manipulation of organisms.
• Option D: "DNA alteration" is a vague term; genetic engineering is the specific, recognized term for this type of DNA manipulation in organisms.

Answer:

A. Genetic engineering
