Q: Do prokaryotes have a cell nucleus?
A: Generally not, however a small number of exceptions have been found.
Q: What is the genetic material in prokaryotes?
A: Prokaryotes possess genetic material in the form of a single DNA loop called a Nucleoid that floats around freely inside the cell.
Q: What type of bacteria includes Cyanobacteria?
A: Cyanobacteria (formerly known as blue-green algae due to their photosynthetic capacity) is one type of bacteria.
Q: How do prokaryotes reproduce?
A: Prokaryotes reproduce without fusion of gametes.
Q: Do prokaryote cells have membranes?
