The Basis of DNA Technology

Question 14 • Biology_A_IC

Which best illustrates the importance of DNA technology?

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

Explanation

DNA technology can be used to change an organism’s genetic material to give it a useful trait. A potato plant modified to resist pests illustrates this because its DNA has been altered for a practical benefit. A mechanical limb is not a DNA change, and a natural mutation or a designed flower pattern does not necessarily involve DNA technology.
