A prion is a small infectious particle that contains a protein. These contain no DNA or RNA. These cause Creutzfeldt-Jakob disease, Scrapie in sheep and Kuru. These are deadly and progressive nerve wasting diseases.
An unicellular organism is an organism that does not have a nucleus. Two types of these organism is bacteria and archaea.
They are called eukariyotic.Cells without nucleus called prokariyotic.
a cell that does not contain a nucleus is called a prokaryotic cell, so an organism without a nucleus is called a prokaryote
Since viruses are not living, they do not have any organelles like a nucleus. They do have RNA or DNA but neither is in a nucleus.
Both bacteria and viruses are prokaryotic, which means they do not contain a nucleus. Both viruses and bacterium are not cells.
Cells with a nucleus are known as eukaryotes. Cells without nulcei are called prokaryotes.
These cells are called prokaryotic.
bacterium
Cells with a nucleus are called eukaryotic cells, while cells without a nucleus are called prokaryotic cells. Eukaryotic cells have their genetic material enclosed within a membrane-bound nucleus, whereas prokaryotic cells have their genetic material free-floating in the cytoplasm.
the viruses doesn't have is no nucleus, cytoplasm,organelles, or cell membrane.
The atom is the smallest unit containing a nucleus. However, this is not considered living. The smallest living thing in the world (besides viruses) are a parasitic Bacterium called Mycoplasma Gallicepticum.
It is called a Eukaryotic cell
