A starting signal for cell division: Molecular switch ensures that cells divide at the right time
About 100 cells divide every second in our body. A key protein in cell division is a protein kinase termed Plk1, because it activates other proteins involved in this process. Plk1 is also ...
Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

How chromosomes shape up for cell division: Scientists reveal DNA loop formation mechanisms
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...
