What are genes, and how do they make a person unique?

Prokaryotes do not contain membrane-bound organelles or genetic information within nuclei, while eukaryotes contain membrane-bound organelles and do store their DNA in nuclei. Both types of organisms may be producers and consumers

Explanation:

Cells are the basic microscopic elements of all organisms. There are two cell types: Prokaryotes and Eukaryotes.

Prokaryotic describes single-celled microorganisms that do not have a cell nucleus or other organelles surrounded by membranes.  Eukaryotes are either single-celled or form complex multicellular bodies. They contain many membrane bound organelles, and their genetic information is stored within a nucleus.

Both groups may contain structures like cell walls, and carry out heterotrophic or autotrophic nutrition.
