Answer:
Tris, or tris(hydroxymethyl) aminomethane, is a common biological buffer, used throughout the DNA extraction process. During extraction from any number of sources, DNA is pH sensitive. During cell lysis, removal of unwanted cellular components and precipitation, tris is used to maintain a stable pH
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:
Vitamins and minerals are considered essential nutrients—because acting in concert, they perform hundreds of roles in the body. They help shore up bones, heal wounds, and bolster your immune system. They also convert food into energy, and repair cellular damage.
Answer:
Explanation:
eight out of the 9 trainees prescribed the antibiotics, whereas 7 out of the 12 GPs did so. On the basis of a Bayesian analysis, these results yield reasonable statistical evidence in favor of the notion that experienced GPs are more likely to withstand the pressure to prescribe antibiotics than trainee doctors.
