The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious difference ...

As viewed from a human perspective, nature has done some ingenious engineering to overcome some of the obstacles it has faced. Take the evolution of sex, for instance. To make the move from asexual to ...

Mitosis and meiosis are both processes by which cells reproduce, but there are distinct differences between the two. While new cells are generated during mitosis, meiosis is a special type of cell ...

In the process of replicating themselves, cells have another choice: do they want to make an identical copy and be left with two cells? Or do they want to make four “half-copies”, in preparation for ...

The completion of mitosis is governed by the dephosphorylation of cyclin-dependent kinase (Cdk) substrates and by the ubiquitination of anaphase-promoting complex (APC) substrates. The order in which ...

Scientists have gained new insight into the process of mitosis in mammalian cells. Researchers have succeeded in deciphering a heretofore unknown mechanism that plays a key role in cell shape changes ...

Just how a dividing cell rebuilds the nuclear envelope, the protective, functional wrapping that encases both the original and newly copied genetic material, has been a source of controversy for the ...

I loved my science courses when I was in Junior High School; we leaned to make batteries, how molecules combine to form the world we see around us, and basically I got a picture of where we stood in ...
