Naked Virus Correct Answer-A virus without an enclosing envelope, consisting only of a nucleocapsid Capsid Correct Answer-The protein shell of a virus that encloses its genetic material Icosahedral Symmetry Correct Answer-Is a limited (closed) structure and allows packaging of only limited genome sizes Quasi-Equivalence Correct Answer-The relationships between capsid proteins structures are similar but not identical Haemagglutination Correct Answer-Is a specific form of agglutination...

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 ...

Why is it important to study viruses? correct answer: 1) Most abundant biological entity 2) Viruses have shaped history 3) Viruses infect all organisms 4) Viruses can cross species Wha are the common properties unique to viruses? correct answer: 1) Simple structure 2) RNA/DNA genome in a protein coat (capsid) 3) Capsid symmetry 4) Acellular obligate parasites 5) Sometimes have another membrane layer (envelope) What are the structural characteristics used to classify viruses into f...
