Viruses vs Cells
Viruses, Virus Structure, and Cell Comparison
| Question | Answer |
|---|---|
| The outer protein coat of a virus | capsid |
| All viruses are made of nucleic acids and ___________. | proteins |
| A "non-living" particle made of DNA/RNA surrounded by a protein coat;infects living cells and can only reproduce with the help of living cells | virus |
| A virus that infects a bateria cell | bacteriophage |
| Infection cycle that ends in the bursting and destroying of a host cell | lytic cycle |
| Intructions for new copies of a virus; these are contained inside the capsid | viral DNA/RNA |
| Infection cycle in which viral DNA fuses with the host cell DNA; host cell replicates with viral DNA | lysogenic cycle |
| Viral diseases can be prevented with a _______________ (weakened or killed virus) | vaccine |
| Protects and surrounds the DNA/RNA of a virus | protein coat (capsid) |
| Found only in a cell; controls cell's activties and contains genetic material | nucleus |
| Controls and blocks the growth of bacteria NOT a virus; given by a doctor when you have a bacterial infection | antibiotic |
| A cold, the flu, AIDS, measles and polio are considered _______________________. | viral diseases |
| Botulism and strep throat are considered _________________________. | bacterial diseases |
| Jellylike substance found ONLY in cell; holds all organelles in place | cytoplasm |
| A structure on a virus which binds to the receptor sites of a cell; "tricks" the cell to allow the viral DNA inside | surface proteins |
| Fibers found on a bacteriophage virus; they help the virus to attach to the host cell | tail fibers |
| Organelles found ONLY in cells and are responsible for the assembly of proteins | ribosomes |
| Flexible barrier found ONLY in cells; regulates what enters and leaves the cell | cell membrane |
| Smallest form of life that has internal organelles to assist with life processes | cell |
| DNA/RNA; found in BOTH a virus and a cell | nucleic acids |
