Exam 5: Viral Structure and Multiplication

Viral nucleic acids include which of the following?

The primary purpose of viral cultivation is ________.

An ideal antiviral drug would be one that killed the host cell,effectively preventing the virus from replicating.

Viruses attach to their hosts via ________.

One of the principal capsid shapes is a 20-sided figure with 12 evenly spaced corners referred to as a(n)________ capsid.

Which of the following will not support viral cultivation?

Uncoating of viral nucleic acid ________.

You are running an experiment in calf serum,which cannot be autoclaved because proteins essential to your protocol will be denatured.  You decide to filter sterilize the serum since the 0.22μm filter is small enough to block any bacteria that may contaminate your tissue culture.  The success of this procedure hinges on the fact that ________.

Which of the following is not a characteristic of a transformed cell?

A common method for cultivating viruses in the lab is to use in vitro systems called ________ cultures.

What structures are used by bacteriophages to attach to host cell receptors?

Respiratory syncytial virus (RSV)is a common respiratory virus that causes mild cold-like symptoms in most individuals,but can be more serious in infants and the elderly.RSV is so-named because ________.

Viruses are unable to multiply outside of a host cell.

The development of antiviral drug therapy is difficult because ________.

Oncoviruses include all the following except ________.

An RN in a pediatric emergency department performs a triage patient on a 13-month-old male. The patient's father states he had difficulty waking his son from a nap that afternoon. Additionally, the infant had difficulty crawling and had difficulty with feeding the following morning. The RN observes that the patient has a weak cry. Upon further assessment, the patient's father noted that the infant had ingested fresh honey on his toast at breakfast yesterday. The medical team suspects Clostridium botulinum infection due to the ingestion of bacterial endospores. -Even though it is a bacterium,Clostridium botulinum can be made more pathogenic once infected with a(n)________.

When a bacterium acquires a trait from its temperate phage,it is called ________.

Viruses are ultramicroscopic because they range in size from 2 mm to 450 mm.

When a virus enters a host cell,the viral genes redirect the genetic and metabolic activities of the host cell.

T-even phages ________.
