Most of the time, when a cell in our bodies divides, each new cell carries a complete set of chromosomes. The cells involved with human reproduction, however, carry only half after division occurs. In ...

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 ...

Without centromeres, cells cannot divide properly and the overall process of mitosis fails. Why are these small chromosomal regions so essential to such a major cellular process? With a few exceptions ...

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 ...

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 ...

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 process of mitosis has made more clear, thanks to recent research. A new study describes how Topo 2, an enzyme that disentangles DNA molecules and is essential for proper cell division. At this ...

A biological process taught to every pupil studying science at high school has just become a little more complicated thanks to a new discovery. Scientists have found that a protein called RASSF7 is ...

Embark on an exciting journey to uncover the wonders of cell division as we explore mitosis and meiosis. In this captivating explanation, we'll delve into how cells divide and pass on genetic ...
