What is the importance of microtubules in cell division? (1 point)
O They reform the nucleus in the divided cell.
O They provide a pathway for organelles to move into the newly formed cell.
O They start the process of cytokinesis.
O They organize and pull the chromosomes apart.

Respuesta :

The importance of microtubules in cell division cannot be understated, they are a vital structure that organizes and pull apart the duplicated chromosomes during cellular division.

Aside from being a vital structure for the entirety of cellular life as they complete a wide variety of necessary cellular functions, microtubules are also necessary to complete a proper cellular division and ensure the correct chromosome numbers for each daughter cell.

The microtubules are responsible for forming the mitotic spindle. During the cell cycle, the chromosomes of a cell are duplicated. Later, during cellular division, it is necessary to separate these duplicated chromosomes in order to avoid abnormal chromosome numbers. This function is done by the mitotic spindle made from microtubules.

These microtubules form around the duplicated chromosomes, organize the chromosomes along a line, and then pull apart the sister chromatids in order for the cell to divide into its daughter cells while maintaining the correct chromosome count for each cell created.
