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

The National Institutes of Health (NIH) set up a study to determine whether large doses of vitamin C would shorten the length of time it takes to recover from a cold. Three thousand volunteers were split into two groups. For two weeks, members of Group A took 3,000 mg of vitamin C daily. Group B received 3,000 mg of a placebo. At the end of the two-week period, the researchers inserted live cold viruses directly into the noses of all the volunteers. The volunteers in both Group A and B continued to take their daily pills. All the volunteers got colds, and there was no significant difference in the length of time the colds lasted. What is the experimental group in this example? Select the best answer. Group B. Three thousand volunteers. Group A. The live cold virus. Length of time the colds lasted. The vitamin C. Size of pill (3000 mg).

This is a hypothetical scenario. A recently emerged virus has been transmitting and mutating rapidly in humans throughout the world. If a vaccine that stops transmission of all current circulating variants of the virus in humans is utilized and herd immunity is achieved throughout the world, would this essentially stop 1) further transmission of the virus; 2) further mutation of the virus, respectively? Why/why not? Please answer the question succinctly and in bullet points!
During a lytic cycle, viral DNA replication occurs without phage production or the death of the cell while during the lysogenic cycle many copies of the phage are produced within the bacterial cell, the bacterium breaks open. Select one: True False
An antigen acts is a molecule that acts like a name tag, allowing the immune system to recognize the cell it is attached to. The name tag might say: "Hello I'm... a deadly virus," or “Hello I'm... a healthy human cell." It is very important that an antigen for a deadly virus and a healthy human cell are very different, so that the immune system does not make a mistake and attack healthy human body cells. Which of the following molecules do you think would make good antigens for recognizing a pathogen? Justify your answer. You may choose more than one. 1) a cell wall protein 2) a piece of DNA inside a cell 3) a protein that is part of a flagella 4) a uniquely shaped protein that is part of a virus 5) a protein that is only made by prokaryotic cells 6) a protein that is only made by eukaryotic cells

Which of the following statements is true regarding the M13 virus coat protein? (Refer to the figure) 9 Positive R, K, H Negative D, E 5 10 15 20 25 30 35 40 45 50 The amino acids in the beginning of the chain should face the DNA. The amino acids towards the higher number end of the chain should face the DNA. The amino acids at the higher end of the chain can destabilize the DNA. The amino acids at the beginning of the chain can stabilize the DNA.
(there are multiple right answers to this homework question but I can't tell which one is right) You are designing a phage therapy for a cystic fibrosis patient with an multi-antibiotic resistant Mycobacterium infection. The Mycobacterium infection is preventing the patient from taking immunosuppressant drugs that are needed for a successful lung transplant. The idea is that introducing the right phage to the patient will kill the Mycobacterium cells and allow the patient to go on immunosuppressant drugs that will ensure the new lung is not rejected by the body. In the first step of your phage therapy design process, you isolate the exact Mycobacterium strain from the patient. What is the most important thing must you establish next about this bacterial isolate? That the isolate is genomically stable so you can study it That the isolate is similar to Mycobacterium in other patients That the isolate rapidly evolves due to horizontal gene transfer That the Mycobacterium is…
