Cohesin opens up for cell division

Scientists at Nagoya University, with colleagues at Kyoto University in Japan, have uncovered a mechanism that allows a protein complex to bind to DNA without impeding some of the important processes of cell division. Their ...

Biologists discover a trigger for cell extrusion

For all animals, eliminating some cells is a necessary part of embryonic development. Living cells are also naturally sloughed off in mature tissues; for example, the lining of the intestine turns over every few days.

Sixty-year-old question on DNA replication timing sequence answered

Over the last 60 years, scientists have been able to observe how and when genetic information was replicated, determining the existence a "replication timing program," a process that controls when and in what order segments ...

Researchers shed new light on DNA replication

In preparation for cell division, cells need to replicate the DNA that they contain. A team of researchers from TU Delft, collaborating with investigators from the Francis Crick Institute in London, has now shown that the ...

How human cells coordinate the start of DNA replication

Cold Spring Harbor Laboratory (CSHL) President and CEO Bruce Stillman has been dissecting DNA replication, a critical step in cell division, since the 1980s. His lab studies how Origin Recognition Complexes—ORCs—coordinate ...
