Question

What is the typical structure and location of the bacterial chromosome (nucleoid)?
Options
A Multiple linear DNA molecules enclosed within a nuclear membrane
B A single, closed-circle DNA molecule concentrated in a non-membrane-bound region
Correct Answer
C Segmented DNA molecules distributed throughout the cytoplasm
D DNA molecules tightly associated with histone proteins
Correct Answer

Option B is the correct answer.
