Which observation provides evidence that a cell is most likely a prokaryote

it has dna that is not contained within a nucleus

Explanation:

The word prokaryote is of Greek origin and means “anterior nucleus” or “before having nucleus”. This meaning gives the impression that it is a primitive structure, and that is exactly what these organisms are about. When compared to eukaryotes, prokaryotic cells are simpler, which leads to the belief that they are more primitive elements in evolutionary history. Thus, it is believed that the first cell was that of a prokaryote being.

The composition of this cell group has few membranes, in general, the only one present is the one that delimits the cell. The prokaryotic cell is characterized by the absence of very well-known and common membranous organelles, such as mitochondria, chloroplast, Golgi complex and nucleus. Regarding the absence of a nucleus, the DNA of this cell is not separated from the cytoplasm by a nucleus.

The prokaryotic cell has a plasma membrane, cytoplasm, free and non-compartmented genetic material (DNA) and ribosomes.
