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...

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 _____...

Microbiology Exam 2 xam Questions And Answers (Verified And Updated) Are Viruses Living or Nonliving? - answerThey 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"? - answerWhen they are inside of a host cell. When inside, their nucleic acid (ONLY RNA OR DNA) become active. *Virus replicates Obligatory Intracellular Parasites - answerRequire livinghos...

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....

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 - ...

Virus - infectious particle consisting of genes packaged in a protein coat non-living obligate intracellular parasite A Virus is not living - True Viruses can't produce or carry out metabolism outside of a host cell - True Where do viruses reproduce? - In living cells Viruses=parasites - Obligate parasites - require a host cell for replication All living organisms have viruses: - prokaryotes and all varieties of eukaryotes Bacterial viruses - Bacteriophage; phages Virus Sizes - Small ...
