Movement of the chromosomes during anaphase would be most affected by a drug that
My name is Ann [436]

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.
