Question

Non-dividing bacteria have .......... chromosomes and may have extra circles of .......... called plasmids.

• A. one; RNA
• B. one; DNA
• C. two; RNA
• D. two; DNA

Answer 1

The correct option is B one; DNA

The bacterial genome is composed of a single molecule of chromosomal deoxyribonucleic acid or DNA and is located in a region of the bacterial cytoplasm visible when viewed with an electron microscope called the nucleoid. Unlike the eukaryotic nucleus, the bacterial nucleoid has no nuclear membrane or nucleoli. In addition, bacteria also contains many extra circular DNA known as plasmids.

So, the correct option is 'one; DNA'.
