B Its genetic material is represented as naked Deoxyribonucleic Acid
D It is the smallest bacterial cell.
Mycoplasma is the smallest bacterial cell ever found. Bacterial cells are also known as prokaryotic cells because they are single-celled organisms, and the organisation within them is very primitive compared to eukaryotes. They don't have a defined nucelus or a nuclear membrane, so their genetic material (DNA) is floating around in the cytoplasm. Despite being primitive, they do have their own protective layers, mainly a cell wall, along with the cell membrane.
