Hi, I'm Michael Maidaa, and this is "what pathogen does not have a nucleus?" A pathogen, or sometimes called an infectious agent, is a broad term, meaning some biological agent that causes disease or illness. There are several different types of pathogens, hosts, and different pathways. The two main types that do not have a nucleus are subcellular pathogens and prokaryotes. Subcellular pathogens, the main ones would be viruses, and prions. Prions are basically just misfolded DNA, so they don't even, oh, misfolded proteins, so they don't even contain any nucleic acids, let alone have a nucleus. Prokaryotes, on the other hand, are a full cell. However, no prokaryotes contain a nucleus. An example of a prokaryote that's a pathogen is bacteria. So, to recap, there are several different types of pathogens, but only certain types do not have a nucleus, subcellular pathogens and prokaryotes, with prions simply being misfolded proteins. I'm Michael Maidaa and this has been "what type of pathogen does not have a nucleus?"
