Question Detail
Question
The region where the DNA lies freely in the cytoplasm of prokaryotes is called: A. Nucleus B. Nucleoid C. Nucleoplasm D. Mesosome
Correct Answer
Option B is the correct answer.
Detailed Explanation
Prokaryotes do not have a membrane-bound nucleus. Instead, their single, circular chromosome is concentrated in an irregularly shaped region within the cytoplasm called the nucleoid. Mesosomes are infoldings of the plasma membrane, not the location of DNA.
Hint
It sounds like 'nucleus' but without the 'us' – it's the DNA-containing region, not an organelle.
