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 ...

Cells have evolved careful checks to ensure DNA is copied only once, but how they switch on replication at the right moment ...

Embryonic stem (ES) cells are pluripotent stem cells that can produce all cell types of an organism. ES cells proliferate rapidly and have been thought to experience high levels of intrinsic ...

Researchers shed new light on G-quadruplexes, a type of secondary DNA structure that has attracted attention as a potential therapeutic target in cancer. Every day, billions of cells in your body ...

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction. Until now, researchers believed that these so-called SMC motors that make ...

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 ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that quantitatively detects and maps reversed DNA replication forks with ...
