Question 10 • CMS 2026-2027 Biology CREDIT RECOVERY

Which best illustrates the importance of DNA technology?

Answer
A
an elephant calf that has a mutation in its DNA
B
a potato plant that is modified to resist pests
C
a flower that has a pattern designed by people
D
a dog that has a mechanical limb

Explanation

DNA technology can deliberately alter an organism’s genetic material to give it a useful trait. Modifying a potato plant so it resists pests is an example of using that technology. A mechanical limb is not a change to DNA, and a naturally occurring mutation is not necessarily the result of DNA technology.
