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 ...

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 ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

King Abdullah University of Science & Technology (KAUST)Mar 19 2025 Reviewed For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their daughter ...
