Mitotic spindle

The mitotic spindle is a structure made of microtubules that forms inside a cell during cell division. Its main purpose is to ensure that each new cell receives an accurate copy of the parent cell's genetic material (DNA). The spindle acts like a guiding framework, attaching to chromosomes and aligning them in the center of the cell. Then, it pulls the duplicated chromosomes apart to opposite sides of the cell, allowing the cell to divide into two genetically identical daughter cells. This process is essential for growth, development, and tissue repair.
