What is the macromolecular composition of a bacterial virus or bacteriophage such as phage T2?
Probably the key to this question is understanding the different acronyms and the answer choices provided. So we have HBV and HCV, and we have ahh V One and H H V two. So HPV is going to be our hepatitis B virus. Likewise, HCV is are going to be our hepatitis C virus. H H V one and two are renames of the HSV one and HSV two herpes simplex virus. It was renamed to the human herpes virus recently, So here we have herpes, basically the Type one and herpes type two. So hepatitis B and C can both be eliminated because these are associated with an inflammation of the liver rather than sores of any sort in the mouth between herpes one and herpes, too. Our best choice is for herpes. One herpes one typically infects the oral cavity, whereas herpes, too. It's typically Soares, located on the genitals. So here the best answer choice for this question is C for human herpes virus one
To answer this question. We have to be familiar with the structure off mycoplasma. So Michael plasma are going to be he's bacteria that are going to be resistant to a particular antibiotic. And specifically this antibiotic that they're resistant to is beta lacked him. Yeah. Now, the resistance isn't something that is, uh, kind of an acquired resistance over time over many generations. But this is more of a resistance because the antibiotic beta lacked him. Uh, the class of antibiotics beta exam class is supposed to target a particular feature of bacteria. And these mycoplasma who act this particular feature that feature that we're talking about is a South war. So, Michael plasma black. So walls, they don't have any cell walls. Now, why is this important? Well, because beta lacked him targets bacterial. Okay, cell walls, weakening them. And by weakening the cell walls, it is able to kill those bacteria. That's how the beta lacked him. Antibiotics work. So why would they be ineffective? Well, if you simply don't have a cell wall to weekend, then the antibiotic is not able to execute its function properly because it just doesn't have any target anymore. So therefore, debate elect him. Antibiotics are ineffective against mycoplasma
So if a bacteria faraj so basically a virus that infects bacteria in fact, a bacterial cell, we're trying to figure out what de virus would be like. Now, the virus is known to have a tea to protein coat, but that the tea for DNA was inserted into that protein coat so the virus is going to infect the cell. Normally, the tea too protein coat is going to attach to the cell and start injecting the genetic material into it. And again that genetic material that is going to inject is going to be the tea for DNA. So is going to insert E for DNA and to de bacterial. So and within this cell Ah, basically, the back the virus is going to hijack the bacterias Ah, replication system. And so it's going to replicate its DNA. So this is going so there you're going to have more viral DNA coming from your injection as D cell is hijacked to replicate the viral DNA, and then the DNA is going to be transcribed in tow, Arnie, and then translated into proteins and these proteins and code for what will become the viruses coat. The virus is protein coat. So since it's tea for DNA that you're getting, you're basically instructions to create the protein coat. You're going to get a tea for protein coat. So even though a P for protein, um, coat was used for the initial injection we're going to get is tea for proteins that are going to house your tea for DNA inside of them.
Hello nephritis is a severe infection of what, what the hint here is in the name nephritis means we're looking at a kidney infection. So the answer is it's an infection of the kidneys, but what is pilo nephritis? So typically the cause of agents is some kind of organism usually found in bowels reaching the urinary tract. So um fell that syria reaching urinary threat, it's effectively the result of a uTI urinary tract infection. If untreated, they can reach for kidneys and kidney kidney infection, which would give you a lot of pain uh frequent urination and burning with urination and in severe cases sepsis or kidney failure, they are treatable, but it's much better to treat the new T as soon as possible. So if you get one guest treated, stay hydrated. Yeah.
