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 is a fundamental process essential for bacterial growth and survival. Initiation begins at the chromosomal origin (oriC), where the conserved initiator protein DnaA assembles into an ...

MSK researchers are shedding new light on G-quadruplexes, a type of secondary DNA structure that can cause DNA replication to stall. The structures are a potential therapeutic target in cancer. Image ...

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

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

DNA is the molecular basis of heredity, the inherited traits that pass between generations in a person's family tree. Embodied in the sequence of base pairs, DNA carries information between ...

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 ...
