Consider an animal cell in which motor proteins in the kinetochores normally pull the chromosomes along the kinetochore microtub

ules during mitosis. Suppose, however, that during metaphase, this cell was treated with an inhibitor that blocks the function of the motor proteins in the kinetochore, but allows the kinetochore to remain attached to the spindle. The inhibitor has no effect on any other mitotic process, including the function of the nonkinetochore microtubules.Answer yes or no to the following three questions concerning this animal cell that has been treated with the inhibitor:1. Will this cell elongate during mitosis? A / B.2. Will the sister chromatids separate from each other? A / B.3. Will the chromosomes move to the poles of the cell? A / B.A. noB. yes

Answer:

The correct answer is "yes, yes, no" or "B, B, A".

Explanation:

In the hypothetical situation stated in the question, an inhibitor blocks the function of the motor proteins in the kinetochore, but allows the kinetochore to remain attached to the spindle. The animal cells treated with this inhibitor would be able to elongate during mitosis, their sister chromatids would separate from each other but the chromosomes would not move to the poles of the cell. The inhibitor only action is to block the function of the motor proteins, and since the motor protein function is to move the chromosomes to the poles of the cells, this will be the only activity that will be affected during cell's mitosis.

Answer:

An evaluation of the impact of immunoenzymatic assays on immunochemical-based analytics in the last 4 decades, in the detection of infectious agents or products associated with their presence and (or) pathogenic activity was made. In addition, there is an incursion into some designs and formats that these immunoassays have had since electrochemical detection methods, tests to detect proteolytic activity of microbial origin and its inhibitors as possible therapeutic targets, direct triple antibody immunoassays to achieve greater sensitivity, alternative developers of enzymatic activity, trials for the study of viral serology with a minimum of determinations, as well as proficiency tests to evaluate the efficacy of controlled vaccine candidates in selected peptide combinations. It was concluded with a quick vision of the immediate future of this type of immunoassays in the light of emerging analytical detection technologies.

Answer:

Autonomic

Explanation:

<em>The autonomic nervous system is a section of the peripheral nervous system that specializes in the regulation of various body processes that requires no efforts. </em>
