Researchers have found a molecular mechanism that prevents multiplication of potentially dangerous cells by measuring the duration of mitosis. They have shown that this mechanism -- the Mitotic ...

It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate everything inside of them, including their neatly packaged DNA, then split in half.

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 ...

Animals and fungi predominantly use two different modes of cell division -- called open and closed mitosis, respectively. A new study has shown that different species of Ichthyosporea -- marine ...

A cell copies all of its DNA, gears up to split in two, and then just… doesn’t. It sits there, swollen with a double genome, and nobody notices. This kind of silent failure has been observed in labs ...

When we talk about memories in biology, we tend to focus on the brain and the storage of information in neurons. But there are lots of other memories that persist within our cells. Cells remember ...

Cell division is a precise process, but sometimes it can be impaired, allowing diseases such as cancer to develop. Researchers at Okinawa Institute of Science and Technology (OIST) in collaboration ...

Until now, cells dividing by mitosis were thought to grow round and then split into two identical, spherical daughter cells. New research has found that some cells are isomorphic, meaning they retain ...

An organism grows and repairs its body using a form of cell division known as mitosis. To divide, a cell must replicate the chromosomes, which carry the DNA (the instructions needed to build the body) ...

DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes. These histones carry numerous chemical modifications that act as molecular ...
