Which of the following highly contagious viruses is a single-stranded ribonucleic acid (RNA) virus with a helical capsid and envelope and is transmitted by coming in contact with respiratory secretions?
"This is a highly contagious respiratory illness transmitted when an infected person coughs or sneezes virus particles into the air," the health department said in a written statement. "It's so contagious that if one person is sick and spreading measles, nine out of 10 people around them who aren't immune will get it, too."
Group of answer choices
a. Measles
b. Parvovirus
c. Coxsackie virus A
d. Rhinovirus
In electron micrographs of HSV infection, it can be seen that the intact virus initially reacts
with cell-surface proteoglycans, then with specific receptors. This is later followed by viral
capsids docking with nuclear pores. Afterward, the capsids go from being full to being
"empty." Which of the following statements best fits these observations?
The viral envelope is not required for infectivity, since the envelope does not enter the
nucleus.
The viral envelope mediates entry into the cell, the capsid mediates entry into the
nuclear membrane, and the genome is all that enters the nucleus.
Only the genetic material of the virus is involved in the cell's infectivity, and is injected
into the host cell like the genome of a phage.
Viral capsids are needed for the cell to become infected; since the full capsids enter the
nucleus.
Which of the following statements is TRUE concerning viral envelopes?
Only viruses with envelopes have their contents enclosed by a layer containing lipids
Only viruses without envelopes interact with receptor proteins on the surface of the host cell.
Only viruses without envelopes can release their genetic material into the cytoplasm of the host.
Only viruses with envelopes package their genetic material by engulfing it.

- Rhinoviruses, the most common cause of colds, do not have a lipid envelope. Compared to enveloped viruses, these and other nonenveloped viruses tend to remain infectious outside the body longer, are more likely to be spread by contact with surfaces, and are less likely to be rendered harmless by exposure to hand sanitizer or hand washing. Explain how the lack of an envelope could contribute to these characteristics.arrow_forwardRhinovirus, the most common cause of colds, do not have a lipid envelope.
