What happens when a person who is infected with a herpes virus experiences a cold sore or genital flare-up? They are reinfected by exposure to a different, but closely related herpes virus strain. Copies of herpes virus particles that have escaped the immune system periodically experience conditions that allow them to replicate and infect cells. Copies of the herpes virus genome permanently maintained in host nuclei are periodically "activated." They are reinfected by exposure to the same herpes virus strain. COCO

All HPV are non-enveloped double stranded DNA viruses. Their genomes are circular and approximately 8 kilobase pairs in size. Most encode eight major proteins, 6 located in the “early” region and 2 in the “late” region. The “early” proteins are regulatory in function.... Can you please elaborate about the HPV genome in more detail that what I posted above? Thanks.
Which of the following is a similarity between viruses of bacteria (bacteriophages) and viruses of algae? These viruses will enter host cells by membrane fusion. They infect host cells by injecting nucleic acid (i.e., capsid does not enter cell) After replication in a host cell, the newly-assembled viruses will exit the cell by budding. These viruses are taken into host cells by phagocytosis.
Indicate whether the following sentences is either True or False and CORRECT the wrong sentences ( please answer the two questions 1 and 2) : 1. Simian Virus 40 (SV40) is an example of is a circular ssDNA belong to Polyomavirus, was first isolated from primary cell cultures derived from rhesus monkey kidneys, and activates p53. 2. SARS-COV-2 is an enveloped, icosahedral virus that is surrounded by a lipid bilayer and causes COVID-19 pandemic .
Which of the following statements are correct for a class V ssRNA (-) virus? it uses its genome directly for translation it must make the complementary (+) RNA strand to synthesize more of its genome it replicates its genome via classical semiconservative replication it converts its genome to DNA via reverse transcriptase as part of its life cycle
Your doctor has told you that you were recently infected with a PROVIRUS, and no matter what you do, the virus will always be in your body. Explain why a provirus will always remain within your body
Human rhinoviruses are a large family of related viruses responsible for many cases of the "common cold." They are naked, ss(+)RNA viruses. When a person gets a cold, most of the symptoms result from inflammation of the upper respiratory system, caused by the innate immune response to the virus. Describe how the innate immune system would recognize the presence of a rhinovirus infection, and then how its response could lead to cold symptoms.
At a recent trip to the drug store, your pharmacist informs you that the flu vaccines are in. You fear the risk of getting the flu because you've had it before and it wasn't a pleasant experience. You proceed to get the vaccinated for the flu. Which of the following statements regarding your recent vaccination is true? O The vaccine you received protects you from every strain of the flu. O The vaccine you received protects you from the strain of bacteria which scientists believe will be common in the upcoming "flu season". O The vaccine you received protects you from the virus which scientists believe will be common in the upcoming "flu season". O The vaccine won't be effective because you've had the flu in the past and are immune to it.
Which of the following proteins would you expect a mutation in for a virus to infect a new host cell? RNA Dependent RNA polymerase/Reverse Transcriptase/DNA polymerase/etc. Hemagglutinin/Glycoprotein/GP120/etc. Fusion protein Capsid/Nucleocapsid proteins Why? What is that protein responsible for?
Which of the following is NOT true about mad cow disease in cattle and Creutzfeldt-Jakob Disease (the non-genetic type) in humans? Caused by a persistent viral infection over several years Brain pathology looks sponge-like ("spongiform") Represent a slow, progressive, degenerative, fatal disease of the brain Caused by prions, which are infectious proteins without DNA or RNA None of the other four answers (All are true)
