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 ...

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 ...

Researchers demonstrated gene bypass events for mitosis using evolutionary repair experiments. They found a novel connection between genes involved in mitosis and glucose metabolism. This connection ...

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 ...

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 ...

Cell division ensures growth or renewal and is thus vital for all organisms. However, the process differs somewhat in animals, bacteria, fungi, plants, and algae. Until now, little was known about how ...

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 ...

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 film "Mitosis" explores the process of cell division, specifically focusing on mitosis, which is essential for the growth and reproduction of living organisms. It illustrates how a single cell ...
