Every embryo begins with a race against time. Primordial germ cells, the rapidly dividing precursors that ultimately give rise to eggs and sperm, must copy and safeguard their entire genome over and ...

An international collaboration steered by David Cortez, Richard N. Armstrong, Ph.D. Chair for Innovation in Biochemistry, explored how cells tolerate DNA damage and genome instability—and they arrived ...

The Okazaki Fragments That Solved the Mystery of DNA Replication1. The Mystery That Could Not Be Solved by the Discovery of ...

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 ...

At the scale of individual cells, the human body is constantly in motion. Every second, millions of cells divide, particularly in tissues such as the bone marrow, intestine and skin; neurons and heart ...

DNA replication is a tightly controlled process that copies the genetic code, allowing its instructions to be conveyed from one generation of cells to the next. In diseases like cancer, these ...

DNA damage tolerance (DDT), activated by replication stress during genome replication, is mediated by translesion synthesis and homologous recombination (HR). Here we uncover that DDK kinase, ...

Every time a cell divides, it must copy roughly three billion letters of DNA with near-perfect fidelity. That copying process, DNA replication, is among the most demanding operations a cell performs, ...

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 ...
