Answer:
a. True
Step-by-step explanation:
Mitosis is a cellular process where a cell divides into two identical daughter cells. Mitosis is divided into five sequential stages: prophase, prometaphase, metaphase, anaphase, and telophase. During prophase, chromatin condenses into chromosomes, and mitotic spindle fibers start to form from tubulin subunits. Subsequently, during prometaphase, the nuclear membrane disintegrates and spindle fibers attach to the kinetochores of the chromosomes (centromeres). During metaphase, duplicated chromosomes line up along the cell's equator (i.e., the metaphase plate). Subsequently, during anaphase, the kinetochores move toward the cell's poles and sister chromatids separate. Finally, during telophase, kinetochore microtubules of the mitotic spindle disassemble, chromosomes arrive at the poles, the nuclei form at each pole and the chromosomes uncoil.
