Characteristics of bacteria mean the traits exhibited by bacteria-
Bacteria (unique: bacteria) are categorized as prokaryotes, which are single-celled organisms with a straightforward inner framework that lacks a nucleus, and contain DNA that either flows loosely in a bent, thread-like mass called the nucleoid or indistinct, linear parts called plasmids. Ribosomes are the spherical units in the bacterial cell that use the data stored in ribosomal RNA to assemble proteins from specific amino acids.
Two protective covers usually surround bacterial cells: an external cell wall and an internal cell membrane. Some bacteria, like mycoplasmas, have no cell wall whatsoever. Some bacteria may even have the capsule called a third, ultimate protective layer. Whip-like extensions often contain bacteria surfaces— lengthy ones known as flagella or brief ones known as pili— that assist bacteria to move around and connect to a host.
