Hi, I'm Michael Maidaa and this is how is prokaryotic DNA shaped. First, what is a prokaryote? A prokaryote is an organism with no nucleus or membrane bound organelles. It is also generally unicellular. A most common example of a prokaryote is a bacteria. Prokaryote DNA is much different than eukaryorte DNA. It is completely circular. So this would be an example of a prokaryotic DNA. As opposed to human or eukaryotic DNA which is linear. Also a big difference is that prokaryotic DNA only has one origin of replication so this area would be the origin of replication. As you go around, you'll find different genes. So for example this could be gene number one, gene number two, three and four. And this is how prokaryotic DNA would look like. I'm Michael Maidaa and this has been how is prokaryotic DNA shaped.
