Answer:
The infectious units that do not consist of cells and do not possess DNA or RNA are "Prions."
Step-by-step explanation:
Prions are contagious organisms that lack DNA and RNA as well as being cell-free. Misfolded proteins make up the majority of their composition. Diseases like Creutzfeldt-Jakob disease (CJD) in humans and bovine spongiform encephalopathy (BSE or "mad cow disease") in cattle can be brought on by prion proteins. Normal proteins may undergo a conformational shift as a result of the misfolded prion proteins, which will cause them to take on the abnormal shape as well and spread the disease.
