Virology Exam 1 What is the ultimate function of the Virion? - correct answer To transmit the genome, which is inside, efficiently and effectively to the host organism. What are some viral properties that are important for survival of the virus in nature? - correct answer 1. Must have protection from chemical agents, physical damage, and enzyme damage. 2. Must contain a capsid so that it can recognize essential receptors that will lead to its replication and recognition with the host cell....

-minuscule, acellular infectious agents carrying DNA or RNA -obligate intracellular parasites CORRECT ANSWER viruses F CORRECT ANSWER T/F viruses have cytoplasmic membranes, cytosol, and organelles virons CORRECT ANSWER when viruses are outside their host they are called what? - possess a protein coat (capsid) that surrounds and protects the nucleic acid (viral genome) CORRECT ANSWER what is the structure of a virus? -shed their protein capsids -exist as naked nucleic acid CORRECT...

True or False: Because the genome is contained within an enclosed space, (much like the nucleus of a cell) viruses are classified as eukaryotic CORRECT ANSWER False. Viruses are neither eukaryotic nor prokaryotic Describe the two basic components of a virus (short answer) CORRECT ANSWER A virus has 1. genomic material comprised of either DNA or RNA and 2. a capsid, a membrane-like protective structure that contains the genetic material, similar to the nucleus of a eukaryotic cell The _____...

Biology 114 Exam 4; Questions & Answers 100% Verified Virus Correct answer-is an infectious particle consisting of genes packaged in a protein coat Capsid Correct answer-protein shell that encloses a viral genome, may be rod-shaped, polyhedral, or more complex shape Viral Envelopes Correct answer-a membrane, derived from membranes of the host cell, that cloaks the capsid, which in turn encloses a viral genome

Are Viruses Living or Nonliving? - They are only considered living when they are inside of a host cell, using their resources and energy. Outside of a host they are considered intert. When are Viruses considered to be "alive"? - When they are inside of a host cell. When inside, their nucleic acid (ONLY RNA OR DNA) become active. *Virus replicates Obligatory Intracellular Parasites - Require livinghost cell in order to multiply - Such as Viruses. Defining a Virus - ...

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 ...

Which of the following is a property of viruses that defines them as unique organism: a) Do not contain or code for proteins synthesis or energy-generating mechanisms b) Have a wall composed of LPS c) have an icosohedral capsid Correct Answer-a) Do not contain or code for proteins synthesis or energy-generating mechanisms T/F: Enveloped viruses are normally more resistant to dry conditions than non-enveloped viruses. Correct Answer-False (Non enveloped are more resistant)

What kind of cells can viruses infect? ~~> viruses infect every type of cell, including bacteria, algae, fungi, protozoa, plant, and animals Are viruses alive? ~~> two sides of the debate: 1. since viruses are unable to replicate independently from the host cell, so no, not alive 2. even though viruses do not exhibit most of the life processes of cells, they can direct them, so more than inert (lacking strength/ability to move) and lifeless molecules viruses are better desc...
