Repetitive DNA near chromosome centers forms a unique barcode for partner recognition. This barcode guides chromosomes to ...

A new discovery by researchers at the RIKEN Center for Biosystems Dynamics (BDR) in Japan upends decades of assumptions regarding DNA replication. Led by Ichiro Hiratani and colleagues, the ...

Every time a cell divides, it must accurately copy its entire genetic instruction manual. Before this process can begin, ...

Before a cell divides, its DNA is replicated so that each daughter cell inherits the same genetic information. The two copies, known as "sister chromatids," are held together by a ring-shaped protein ...

DNA replication and repair mechanisms constitute the foundation of genomic integrity, ensuring that genetic information is faithfully duplicated and maintained across cell generations. Replication ...

New findings suggest the end-replication problem, an old standby of biology textbooks, is twice as intricate as once thought. Half a century ago, scientists Jim Watson and Alexey Olovnikov ...

A molecular illustration of the crowded interior and cell envelope of Escherichia coli. (David S. Goodsell, The Scripps ...

The study highlights an important challenge in cancer research: even very large datasets can contain biological signals that ...

In our bodies, there are trillions of cells. From white blood cells to skin cells, each type has its own specific function which helps us perform tasks and survive. But what makes up these cells and ...
