Question
DNA can be found in all but one
Correct Answer
Option D is the correct answer.
Detailed Explanation
DNA is found in the nucleus, as well as in mitochondria and chloroplasts (semi-autonomous organelles). The question says 'all but one', implying one of the listed locations does NOT contain DNA. Since all three (nucleus, mitochondrion, chloroplast) do contain DNA, the correct answer is 'none' of them are exceptions.
Hint
Do mitochondria and chloroplasts have their own DNA, besides the DNA in the nucleus?
