Quizplus · Accepted Answer

The bacterial chromosome is usually circular and found in a nucleoid, which is a region in the cell where the chromosome is located but is not surrounded by a membrane-bound nucleus. Therefore, both (D) circular and found in a nucleoid are the correct choices. (A) circular is correct but (B) found in a nucleoid is also needed to fully describe the bacterial chromosome. (C) found in a nucleus is incorrect as bacteria do not have a nucleus. (E) both circular and found in a nucleus is incorrect for the same reason.
