Virusis and virology
6 important questions on Virusis and virology
What is a virion?
3 enzymes inside of a virion and function?
- Nucleic acid polymerase: makes viral genome
- Neuraminidases: allows liberation of virus from host.
Eukaryotic and Prokaryotic viral infection destruction mechanisms?
PROK: CRISPR and restricition modification system.
- Higher grades + faster learning
- Never study anything twice
- 100% sure, 100% understanding
2 viral life cycles?
- Temperate mode: virus replicates genome with host genome without killing host.
What is a lysogen?
What is a retrovirus? What are its specific genes? and their functions
It consists of 3 special genes:
GAG: encodes structural genes
POL: encodes reverse transcriptase and integrase
ENV: encodes envelope proteins
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
