Viruses have typical cellular structure like other living organisms. correct answers FALSE Viruses in the extracellular state possess few, if any, active enzymes. correct answers TRUE Which is not true of viruses? correct answers They infect animal and plant cells only. Which of the following is true of viruses in the extracellular phase? correct answers They behave as a macromolecular complex and are no more alive than are ribosomes. A complete virus particle is called a correct ans...

28) Viruses are not the only obligatory intracellular parasites. Describe how the replication of viruses is diferent than cellular organisms that replicate inside of cells, like chlamydiae and rickettsiae. Ans :: Unicellular parasitic cells that need to replicate inside of other cells do not replicate in the same way that viruses do. First of all, unicellular parasites have their own ribosomes to translate their mRNAs and do not use the host cell ribosomes, like viruses do. In addition they ...

Koch’s postulates correlated many diseases with their causing agent/organism. In the 1880’s, Koch’s postulates established four criteria to isolate the responsible disease-causing agent and correlate it to the effects that disease was ca...
