D= nucleic acids and fatty acids.DNA
Answer:
The options are missing, the options are:
A) prevents the duplication of centrosomes. B) prevents nuclear envelope fragmentation C) prevents shortening of microtubules. D) prevents attachment of the microtubules to the kinetochore. E) prevents nucleosome formation
The answer is C
Explanation:
Cell division is a characteristics of all living cells. Whether meiosis or mitosis, the chromosomes separate in the Anaphase stage. Prior to the anaphase stage is the metaphase, where spindle microtubules attach to the kinetochores of each chromosome and aligns them at the centre of the cell called METAPHASE PLATE.
Thus, since the aligning of chromosomes at the metaphase plate has to do with attachment of microtubules to chromosomes' kinetochores, the drug that will hinder movement of chromosomes to opposite poles will not stop formation of microtubules. Instead, it will prevent the formed microtubules attached to each chromosome from shortening, as it is the shortening of microtubules that facilitates the pulling apart of the chromosomes they are attached to.
Enzymes are catalysts, which means that they make chemical reactions go faster, but are not changed by the reaction. For example, digestive enzymes cause food that you eat to be broken down much faster than would occur without them, but they are not broken down in the reaction they are speeding up.
Research has shown that people who have a chronic disease or have low energy levels also have lower enzyme content in their blood, urine, and tissues. While there is clearly a direct relationship between disease states and a person's enzyme levels, only recently has the NATURE of that relationship been better understood. Researchers began to question if a person's enzyme levels were low because they were sick or were they sick because their enzyme levels were low. The researchers found something surprising.
<span>A person may not have a low enzyme content because he is sick or old, but instead, the reason a person may be sick or old is because of low enzyme content.</span>
