Which of the following is characteristic of the lytic cycle? a) The virus-host relationship usually lasts for generations Ob) The viral genome replicates by destroying the host cell Oc) A single phage being released at a time d) Viral DNA is incorporated into the host genome

Antiretroviral drugs target various aspects of HIV replication and infection. Which of the following enzymes are targets of antiretroviral drugs? Select ALL that applya).reverse transcriptaseb)integrasec).ligased).proteasee).DNA polymerase

Which structure of a virus protects it from degradation, contains its genome, and enables it to be transmitted outside the host? A) O capsule B) O capsid C) O envelope D) O nucleus E) O spikes

we can stop the biosynthesis stage of the viral life cycle (not the stages before it) by preventing/inhibiting: A) fusion of the envelope and the plasma membrane B) replication and expression of viral nucleic acid/genome C) the virus's attachment molecules from binding to the host cell receptor D) new copies of viral nucleic acid from combining with newly made viral proteins E)budding

A particular animal virus requires the use of DNA polymerase from its host, since it does not possess its own DNA polymerase enzyme. Which of the following assumptions in A-D would likely be correct regarding this virus? A) O This virus could not be a retrovirus type. B) OIt could be a (-) ss RNA virus. C) O It could be a (+) ss RNA virus. D) O The vVirus life cycle very likely includes going to the host cell nucleus. E) O All ofA-D are correct assumptions.

The figure depicts five stages of the lytic cycle. ********* Select the statement that describes stage 3 of the lytic cycle, as shown in the diagram. The host cell synthesizes cellular proteins to prepare for lysis. The host cell incorporates phage DNA into its own genome. The host cell replicates the phage DNA. O The host cell synthesizes proteins that degrade phage DNA.

What does a bacteriophage accomplish with lysogeny? O 1) it allows the bacteriophage to destroy the host cell's DNA. 2) it enables the bacteriophage to take over the cell. O 3) it speeds up the viral infection cycle. 4) it allows the bacteriophage to infect cells it would not normally infect. O 5) the genetic material of the bacteriophage can be passed on to future generations of infected cells.

Why does phage T4 need a lysozyme-like protein in order toinfect its host, and what part of T4 enters the host cytoplasm?

What role do the host cells proteases play in infection, i.e., in viruses gainging access to the host cells cytoplasm?
