Question 17

A transmission electron micrograph of a newly isolated unicellular microorganism reveals a cell wall composed of peptidoglycan, circular DNA free in the cytoplasm, and an absence of membrane-bound organelles. The cell in the micrograph has a measured length of 3.6 cm under a magnification of ×15,000\times 15,000×15,000.

What is the actual length of this microorganism, and how is it classified?
