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 ...

Most cells grow, perform the activities needed to survive, and divide to create new cells. These basic processes, known collectively as the cell cycle, are repeated throughout the life of a cell. Of ...

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 ...

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 ...

Each day, hundreds of billions of cells in our body cycle through a period of growth and division. Yet in that time, only about 30 minutes is spent on the critical orchestration of mitosis, when ...

Scientists have gained new insight into the process of mitosis in mammalian cells. Researchers have succeeded in deciphering a heretofore unknown mechanism that plays a key role in cell shape changes ...

Over the past two decades, researchers have learned that DNA inside the cell nucleus naturally folds into a network of ...

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 ...
