How viruses differ from true living organisms such as bacteria and fungi?.

Viruses are typically not classified as true living organisms by biologists. Viruses have DNA or RNA and protein but are not able to replicate until they infect a host cell. Within the cell they must use the enzymes and molecular building blocks the host cell provides to replicate. Viruses cause disease in all living organisms and they are able to persist outside the cell for extended periods until they can once again infect a suitable host cell.

1. How viruses differ from true living organisms such as bacteria and fungi. They infect the same as any other pathogen that causes disease. Live and obtain the necessary nutrients they need from their hosts but still are not classified as true living organisms and why you believe this is true. Contrast the differences and similarities that viruses have with living organisms such as bacteria and fungi.

2. While we are on the subjects of “unusual” organisms, also comment on prions. How do they compare with viruses and other microbial organisms? What diseases are they thought to cause?

Don’t have to be formal, just answe those two questions directly. Thanks
