| Question | Answer |
| Recognition of Host Cells Suitable for Infection | Normal cell receptors- specific ones allow it to recognize specific tissue |
| Targets for Primary Attachment | Distal parts of protein, away from the cell membrane |
| Secondary Attachment | Usually another component is bound as attachment proceeds, bringing it closer to the cell membrane |
| Receptor Mediated Endocytosis (Virus Type) | Non-enveloped viruses |
| Receptor Mediated Endocytosis (Vesicle Formation) | Clatherin coated pit forms virus containing vesicles |
| Receptor Mediated Endocytosis (Genome Exit) | Vesicle is acidified, virion opens and genome enters cytoplasm |
| Fusion From Without (Virus Type) | Enveloped Viruses |
| Fusion From Without (Genome Entry) | Viral membrane fuses with cell membrane, virus enters cell in genome form |
| Fusion From Without (Envelope) | Remains as a patch of protein on membrane- new virions pick them up as they leave the cell |
| Fusion From Within (Virus Type) | Enveloped Virus |
| Fusion From Within (Vesicle Formation) | Virus interacts with receptor, endocytic vesicle forms around whole virus |
| Fusion From Without (Genome Exit) | Vesicle acidification causes vesicle & viral membranes to fuse, genome is released |
