Question

The bacterial chromosome is ______

A) found in a nucleoid.
B) usually circular.
C) found in a nucleus.
D) both circular and found in a nucleoid.
E) both circular and found in a nucleus.

Answer 1

The correct answer to the question is D) both circular and found in a nucleoid, as the bacterial chromosome is a circular DNA strand located in a specific region called the nucleoid, and bacteria do not have a nucleus.

Step-by-step explanation:

The bacterial chromosome is usually a covalently closed loop of DNA, not organized around histone proteins like eukaryotic chromosomes. Prokaryotes, including bacteria and archaea, have a single circular chromosome that resides within a distinct central region of the cell known as the nucleoid. Because bacteria lack a membrane-bound nucleus, their DNA is not found within such an organelle.

Therefore, the correct answer to the question is D) both circular and found in a nucleoid.
