Introduction to Cell Biology Prokaryotes and Eukaryotes
... Prokaryotes are organisms made up of cells that lack a cell nucleus or any membraneencased organelles. This means the genetic material DNA in prokaryotes is not bound within a nucleus. Additionally, the DNA is less structured in prokaryotes than in eukaryotes. In prokaryotes, DNA is a single loop. I ...
