Document Summary
1918 inluenza pandemic troops and shipping, travelling together in close proximity o o o o o o. Can infect animals, plants, bacteria and archaea all branches of life can be infected. Specialized viruses for specialized organisms atack one paricular cell type. They do not harness and uilize energy no glycolysis, don"t use or produce energy in any way it all comes from the host cell. They do not reproduce these paricles reproduce is only inside a host living cell, they need to use the cellular machinery of the cell that they are inhabiing. Virus genome is small contains very few genes. Boat may be surrounded by an envelope from the host cell. Not membrane bound, it is an envelope picked up when a virus leaves the cell. Acquired as the virus passes through the host cell membrane. As it moves out of the cell some may not pick up an envelope: hiv has rna genome and needs reverse transcriptase.
