The c-terminal domain of RNA polymerase II is the site where other proteins bind to increase the activity of the polymerase. It is the site where transcription is initiated. These functions can be achieved if the domain is not restricted by the globular portion of the protein.
The answer is negative controls. These are groups where no phenomenon is probable. They ensure that there is no effect when there should be no effect. Where there are only two possible outcomes, e.g. positive or negative, if the treatment group and the negative control both produce a negative result, it can be concluded that the treatment had no effect. If the negative control group and the treatment group both yield a positive result, it can be inferred that a puzzling variable is involved in the occurrence under study, and the positive results are not only due to the treatment. In other examples, outcomes might be measured as lengths, times, percentages, and so forth.
Answer:
ATP is a nucleotide consisting of an adenine base attached to a ribose sugar, which is attached to three phosphate groups. ... When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).
D - Allow pH to change drastically.
The reason that we have buffer in our system is to protect AGAINST sudden change of pH
