Question

question 8
scientists have inserted a gene that codes for resistance to a biodegradable weedkiller into a certain plant. which of the following is the most likely benefit of the gene?

a the plant will be able to produce chemicals to kill weeds around it.
b the plant will be able to convert the weedkiller into fertilizer.
c the plant is more likely to survive when exposed to the weedkiller.
d the plant is more likely to die when exposed to the weedkiller.

Explanation:

When a gene for resistance to a weedkiller is inserted into a plant, the main purpose is to help the plant withstand the weedkiller. Option a is incorrect as the gene is for resistance, not for producing chemicals to kill weeds. Option b is not related to the concept of resistance. Option d is the opposite of what the resistance gene would do. Option c makes sense because a resistance - coding gene would make the plant more likely to survive exposure to the weedkiller.

Answer:

c. The plant is more likely to survive when exposed to the weedkiller.
