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 discovered that a long-misunderstood protein plays a key role in helping chromosomes latch onto the right “tracks” during cell division. Instead of acting like a motor, it works more like ...

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

Before cells can divide by mitosis, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Scientists have until now ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Researchers at the Max Delbrück Center have found that a cellular housekeeping mechanism called autophagy plays a major role in ensuring that T stem cells undergo normal cell division. The findings, ...

Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive structural supports. But a new study reveals they play a far more active signaling ...

When a cell divides, it performs a feat of microscopic choreography—duplicating its DNA and depositing it into two new cells. The spindle is the machinery behind that process: It latches onto ...

Researchers at the Max Delbrück Center and the University of Oxford have found that a cellular housekeeping function called autophagy—by which cell components are broken down and recycled—plays a ...

Scientists at the Ruđer Bošković Institute (RBI) in Zagreb, Croatia, have discovered that the protein CENP-E, long believed to act as a motor dragging chromosomes into place during cell division, in ...
