DNA does not float freely in the cell. Instead, it is wrapped around histone proteins to form structures called nucleosomes.

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 ...

An MUSC Hollings Cancer Center research team has identified a protein that helps cancer cells to organize themselves in a way that allows them to successfully navigate the cell division process ...

Before a cell commits fully to the process of dividing itself into two new cells, it may ensure the appropriateness of its commitment by staying for many hours - sometimes more than a day - in a ...

Researchers at the Francis Crick Institute have shown that the "pacemaker" controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...

Cell division is an essential process for all life on Earth, yet the exact mechanisms by which cells divide during early embryonic development have remained elusive—particularly for egg-laying species ...

Researchers at the Francis Crick Institute have shown that the 'pacemaker' controlling yeast cell division lies inside the nucleus rather than outside it, as previously thought. Having the pacemaker ...

If you took high school biology, you probably learned about cell division: a crucial process in all life forms officially called mitosis. For over one hundred years, students have learned that during ...

Processes such as wound healing, hair growth, and the continual renewal of cells all rely on cell division. In this process, chromosomes must be evenly distributed between two daughter cells. Even ...

For sexual reproduction to yield healthy offspring, newly generated oocytes-immature egg cells-must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...

All processes such as wound healing, hair growth, and the replacement of old cells with new ones depend on cell division. During this process, chromosomes inside the cell must be evenly divided ...
