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 ...

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 ...

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 ...

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 ...

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 ...

In the beginning, you were just some genetic material. In order to make you, your biological mom and dad both had to participate in an effort to pitch in one gamete each — a sperm cell and an egg cell ...
