- 1. Viruses that do not form infectious particles within the cell use ____ assembly. The infectious particles are only produced as they bud from the plasma membrane.
- 4. The eIF4E binds to the ___ of the mRNA.
- 6. Partial structural units of a virus needed for assembly.
- 9. Retroviral particles are not infectious until they bud from the cell and complete _____.
- 10. The eIF4G protein serves as a ___ to help circularize the mRNA, linking the cap to the polyA tail.
- 11. Ribosomes bind to the 5’ cap to ______ most translation.
- 14. Viruses all use host cell ___ to produce proteins.
- 17. ____ domains recruit ESCRT machinery to help Enveloped viruses pinch the membrane off from the cell.

- 2. Proteins contain specific signals, amino acid pattern, that help localize proteins to different compartments, such as ___ localization signals.
- 3. Some viral RNAs encode “slippery” regions which cause the ribosome to slip back a base, altering the reading frame, a process called ribosomal ___.
- 5. ____ viral protease cuts eIF4G, preventing cellular protein production and promoting viral protein production.
- 6. Membrane proteins have ____ sequences to direct them to the membrane.
- 7. Virus genomes contain _____ signals in order to ensure the genome is put into the particle.
- 8. The process of an enveloped virus obtaining its lipid membrane.
- 12. Viruses, not being alive, do not grow, they are put together in an _______ line process.
- 13. Viral assembly occurs when proteins and genome are at high enough _____, as nothing happens fast in dilute solutions.
- 15. Some RNAs contain secondary structure that enables the initiation complex to bypass regions and start translation at a later AUG, a process termed ribosomal ______.
- 16. Viruses use polyproteins, suppression of termination, and alternative splicing to increase _____ capacity.
- 19. Most DNA viruses package their genome in the ___ where they replicate their genome.
- 20. Some paramyxoviral proteins have “weak” AUGs which enables multiple proteins to be produced by the same RNA, a process termed ___ scanning.
