Detailed explanation-1: -Definition. The centromere appears as a constricted region of a chromosome and plays a key role in helping the cell divide up its DNA during division (mitosis and meiosis). Specifically, it is the region where the cell’s spindle fibers attach.
Detailed explanation-2: -General Biology (a) The centromere is the region present in a chromosome that separated a chromatid into two distinct arms. This means that the centromere is the portion of a chromosome where chromatids remain attached before the process of cell division initiates.
Detailed explanation-3: -The centromere is the chromosome region that attaches to a spindle fibre at metaphase of mitosis or meiosis and moves to the spindle pole at anaphase, pulling the rest of the chromosome behind it.
Detailed explanation-4: -During anaphase, paired centromeres in each distinct chromosome begin to move apart as daughter chromosomes are pulled centromere first toward opposite ends of the cell.
