Viruses are CORRECT ANSWER obligate intracellular parachutes what do viruses not have CORRECT ANSWER organelles, cytoplasmic membrane, cytosol, can't carry out metabolic reaction, don't grow n size or respond to environment, cannot reproduce independantly virions CORRECT ANSWER when virus is outside of host -possess a protein coat called capsid -capsid surround and protects nucleic acid(viral genome) viral envelope CORRECT ANSWER -present on some animal viruses -phospholipid bilaye...

Virology Exam #1 Properties of a virus - correct answer - Filterable agents (not retained in a filter like bacteria are) - Obligate intracellular parasites - Cannot make energy or proteins independent of a host cell (no generation of metabolic energy) - Viral components are assembled and do not replicate by "division" - Must encode any required process not provided by the host cell - Genomes may be RNA or DNA but not both - Have a naked capsid or envelope morphology Theories on how v...

Portage Learning BIOD 171 Module 6 Study guide with Complete Solutions rated A+ True or False: viruses can be classified as prokaryotic or eukaryotic - False. Viruses are neither prokaryotic or eukaryotic What is an obligate intracellular parasite? - viruses cannot replicate unless inside a living host cell. As a parasite, a virus depends on its living host to provide the framework (proteins, etc) to replicate—to make additional copies of itself. What is a viral capsid? - a membrane-lik...
