Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called ...

Conjugation is the process by which one bacterium transfers genetic material to another through direct contact. During conjugation, one bacterium serves as the donor of the genetic material ...

Both prokaryotic and eukaryotic organisms have developed genetic mechanisms by which they can evolve to adapt to and meet the challenges thrown at them by a changing environment. One process by which ...

Genetic material DNA in a nucleus ... plasmids are found in a few simple eukaryotic organisms. Prokaryotic cell DNA is a single molecule, found free in the cytoplasm; additional DNA is found ...
