- 2. The smallest known viruses (about 18-26 nm in diameter). They are non-enveloped DNA viruses. One of them causes ‘fifth disease’ in children, also called slap-cheek due to the characteristic redness on the cheek.
- 3. is a genus that contains the largest classified virus. Its capsid diameter is about 400 nm (the smallest bacteria are in this range).
- 7. A process by which the cell absorbs (engulfs) certain molecules or particles from the outside environment by enclosing them in a vesicle made of the cell membrane and importing them inside the cell.
- 8. Non-enveloped DNA viruses that can cause upper respiratory infections.
Down
- 1. This viral part is derived from the host cell membrane and offer an extra layer of protection as well as help the virus to infect a new host cell (two words, hyphen in between the two).
- 4. Protein shell that encapsulates and protects the genome of a virus.
- 5. a term used to describe the process of a virus leaving the cell. As the virus envelopes itself in the cell membrane, it is bulging from the cell surface.
- 6. The genetic material of an organism.
