BIO Viruses and Prions

This is a nonliving strand of genetic material with a protein coat.

• virus

• bacteria

• prion

• DNA

Most biologists don’t consider these to be living because they do not exhibit all of the characteristics of life.

• bacteria

• virus

• genetic material

• prions

Viruses cannot make these.

Viruses do not have these to take in nutrients or use energy.

Viruses cannot

• move

• enter a host cell

• exist in cells

• form a capsid

Viruses cannot do this on their own.

• replicate

• form genetic material

• originate from cells

• create nucleic acid

These are some of the smallest disease-causing structures that are known.

• bacteria

• prions

• viruses

• DNA

 Viruses are thought to have originated from parts of these.

Adenovirus infection causes this.

• common cold

• flu

• HIV

• AIDS

The influenza virus causes this.

• common cold
