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 ...
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 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 ...
The process of cell division, or mitosis, has fascinated biologists since its discovery in the late 1870s. Progress through mitosis is traditionally divided into stages that were defined over 100 ...
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 ...
The human body is made up of billions of cells. These cells grow and divide through a process called cell division. There are two types of cell division: mitosis and meiosis. Mitosis is a type of cell ...
