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 ...

Mitosis is a cell division process in which genomic DNA replicates and separates into two new cells. Although it is essential in all eukaryotes, different species use different genes for mitosis. This ...

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 ...

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 ...

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 ...

The primary mechanism by which organisms generate new cells is through cell division. During this process, a single "parent" cell will divide and produce identical "daughter" cells. In this way, the ...

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 ...

Each replicated chromosome is made up of two identical strands called chromatids that are joined together. Each chromatid is a full length DNA molecule. The stages outlined in the following example ...
