What role do microtubules play during mitosis? a) microtubules line up chromosomes at the equator of the cell during metaphase. b) microtubules play a role in the disassembly and reassembly of the nuclear membrane. c) microtubules play a role in the formation of the cell plate when plant cells undergo cell division. d) microtubules play a role in the migration of chromosomes to opposite ends of a dividing cell during anaphase.

D. Microtubules play a role in the migration of chromosomes to opposite ends of a dividing cell during anaphase.

Explanation:

Microtubules are organelles found in eukaryotic cells and in some bacteria cells. They are tiny, hollow and tubular in structure that perform a variety of functions in the cell including maintenance of cell's shape and participation in motor functions of the cell.

Microtubules' functions also include formation of mitotic spindles as well as the movement of chromosomes during cell division.

Hence, the correct option is D.

regulation of gene expression. gene expression can be regulated by various cellular processes with the aim to control the amount and nature of the expressed genes. these regulatory proteins bind to dna and send signals that indirectly control the rate of gene expression
