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.
They are called eukariyotic.Cells without nucleus called prokariyotic.
An unicellular organism is an organism that does not have a nucleus. Two types of these organism is bacteria and archaea.
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.
A eukaryote cell where the nucleus has been removed is termed enucleated. Cells which do not normally have a nucleus are prokaryotes.
These cells are called prokaryotic.
bacterium
A eukaryotic cell has a nucleus and membraned organells, so pretty much everything besides bactirea and viruses are eukaryotic (ones without nucleus are prokaryotic
the viruses doesn't have is no nucleus, cytoplasm,organelles, or cell membrane.
Bacteria are prokaryotic type of organisms. They reproduce by binary fission. In place of nucleus, they have a single DNA molecule called nucleoid. Viruses are living only inside a cell. They divide by producing multiple copies of their DNA.
