A new poison causes animal cells to become misshapen, thus the poison is believed to interfere with some part of the cytoskeleton. Cells exposed to this poison do not undergo mitosis, and neither cilia nor flagella can form. The poison does not prevent muscle contraction. Cells exposed to the poison during early telophase can still undergo cytokinesis.
a) What part of the cytoskeleton is this poison likely to affect?
b)What part of the cytoskeleton does this poison probably not affect?

This most probably affects microtubules.
This does not affect microfilaments
Microtubules function in maintenance of cell shape, motility in the case of cilia or flagella as well as chromosome movement during cell division. The symptoms of the cell exposed to poison show that they are all functions of microtubules.
Microfilaments function in maintenance of cell shape as well as muscle contraction, as muscle contraction is not affected it is safe to assume microfilaments are not affected.
