Question

A scientist is collecting information on an unknown cell type. She notices that all the DNA is floating freely in the cell in a ring-shape and has a couple of plasmids as well. What does this tell her about the cell?
Responses

It is eukaryotic because there is a nucleus holding the DNA.

The correct interpretation of the scientist's observations is:

**It is prokaryotic because there is no nucleus that holds the DNA, and the DNA is arranged in a circular shape.**

In prokaryotic cells, such as bacteria, the DNA is typically found in a circular form and floats freely in the cytoplasm, not enclosed within a nucleus. The presence of plasmids (small, circular pieces of DNA) further supports that this cell is prokaryotic.
