Answer:
The correct answer to the question: Which of the following steps in transcription is most likely affected? Would be: Formation of the open complex.
Explanation:
Depending on the type of bacteria, and the different structures that form the cell, antibiotics of different kinds will seek these structures to either inhibit the cell from performing its normal activities and reproducing, or doing that plus killing it. Of the second kind, called bactericidals, like Rifamycin drugs, these accomplish their purpose precisely by inhibiting steps in the DNA to RNA transcription that will result in the production of erroneous mRNA strands, and therefore, faulty proteins. When these steps are stopped, the bacteria is unable to protect itself, or repair itself, and while the process continues, the antibiotic, in high levels, starts to also eliminate the bacterial cell. Specifically, according to research done, medication like Rifamycin will stop the transcription of DNA into RNA by binding to an RNA transcribing enzyme that is located in the channel formed by the polymerase-DNA complex. In this way, nucleotides that should be added to the mRNA chain are not added and the result that comes out will be really short chains that cannot be translated later into protein.
Answer:
The most correct answer is: It varies in consistency based on the amount of protein fibers and fluid
Explanation:
The extracellular matrix (ECM) is the environment surrounding cells, which is normally composed by fibers (i. e.: collagen, elastin, etc...), soluble proteins and other macromolecules (such as hyaluronic acid) embedded in fluid. The relative concentration and composition of those components conditions, among other things, the physical consistency of the ECM.
- No blood vessel arises from ECM; they derive from specific precursor cells. Additionally, cartilage is an avascular (has no blood vessel) type of connective tissue.
- ECM does provide oxygen and nutrients to diverse tissue, including bone, however bone tissue <em>does</em> have blood vessels.
- Neuronogenesis (generation of new neurons) takes place within the developing nervous system, with neuronal precursor cells being thoroughly surrounded by other cells such as radial glia. Typically, neighboring ECM has a minor or negligible role in this process.
The effects of a right hemisphere stroke may include: Left-sided weakness or paralysis and sensory impairment. Denial of paralysis or impairment and reduced insight into the problems created by the stroke (this is called "left neglect") Visual problems.
<h3>What is impacted by a stroke in the right hemisphere?</h3>
A right hemisphere stroke may result in sensory impairment and left-sided weakness or paralysis. Denial about paralysis or impairment as well as diminished awareness of the problems caused by the stroke are referred to as "left neglect." Visual issues., such as an inability to see each eye's left visual field.
<h3>Does a stroke on the right side impact speech?</h3>
Speech and communication issues are typically seen in right-brain injured stroke survivors. Because of their weak or uncontrolled left side facial and mouth muscles, many of these people have trouble pronouncing spoken sounds correctly. Dysarthria is the term for this.

The doctor will check for the level of activity of TPMT and then adjust her medications according to that.
What is TPMT?
Thiopurine methyltransferase (TPMT) is indeed an enzyme that disintegrates (metabolises) the thiopurine class of medications. These medications are approved to treat various immune-related conditions as well as blood disorders because they suppress the immune system (e.g., leukemia). To ensure that people receiving thiopurine drug therapy can metabolise the drugs, the level of TPMT enzyme activity or the genetics underlying the enzyme's activity are assessed prior to the start of the therapy.
Azathioprine, mercaptopurine, as well as thioguanine are a few thiopurine examples. These drugs are used to treat conditions like autoimmune disorders, inflammatory bowel disease, as well as acute lymphoblastic leukaemia. In order to delay as well as prevent organ rejection, they may also be prescribed to people who have received organ transplants.
Hence the answer is, based on the level of TPMT, the medications will be provided.

I think the doctor noticed how he was breathing in the last two days as it has gotten worse and tested him out. He can exercise, drink lots of water, eat healthier, have plenty of rest and don’t go near things that he is allergic to.
