Question

32. List the factors that can influence the stability of virions in the environment. 33. Briefly explain why all viruses use the protein synthesis machinery of their host.

Answer 1

. stabslely list the factors q virions in the that can influence the envirament. visus arious factors such immediate environment, nswer. It is known that the stability of a vie can be affected by change in its vision of viral nucleic acid structive by various factors as pH ionie strength of the immediate envil Uv - light or heat - Temperature in a crucial factor for vision survivability . - Another important factor influeney vision in the acidity of the environment. - salinity and in content of the environment also lead to the stability of vision survival. - Some factors for a nisur to spread include (stability) Size of the population of opportunity • the number of days contagious the number of people whom an infecked person comes in contact the probality of contrarreeting the virus from contact with an infected person. - the gene Overlap increase exponentially with temperatine such that smaller viruses have proportionally gte gene greater gene ovelap overlap at high tumperature.

- These result indicates ds DNA visus size increases with environmental temperature in much the same way as the call or genome size of many host species. 3 Breifly explain why all visuses use the profeen synthens machinery of their host .. - Viruses are fully reliant on the translational machinery of their host cells to produce the polypeptides that are are essential for visal replicate - The diverse strategies that viruses we to subvert host protein synthen functions and regulate mRNA translation in infected cells. - Consegnently viruses recruit host ribosomes to translate viral mRNAs, typically using virally encoded Furnetions to seize control of cellular translation factors and the host signalling pathway that regulate their actively - Infant, all viruses are obligate intracellular parasites and hence their replication requires host cell fainetin specially protion synthesis machinery. Although the size composition complexity, and functions encoded by this genomes are remarkably diverse all Nisuns rep sely absolutely on the protein synthein machinery for their host cells.
