there is a series of checkpoints in a cell's life cycle, when it assesses whether everything is proceeding according to nature's plan, shows a new research. The discovery was made in yeast cell division by Jonathan Millar, a geneticist at the National Institute of Medical Research in London, the uk. The discovery could lead to a better understanding of how cells specialise to form different tissues and why some become cancerous.

For successful cell division, each daughter cell must get the adequate number of the right chromosomes. To achieve this, a protein scaffold called the spindle, forms inside a dividing cell, to which the chromosomes get attached to. Just before the division, the spindle pulls the chromosomes apart, to the opposite ends of the cell. The newfound checkpoint keeps track of the steps in this chromosomal dance
