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

DNA, often called the blueprint of life, is built from four chemical building blocks known as deoxy-nucleoside triphosphates (dNTPs)—dATP, dTTP, dGTP, and dCTP. Cells constantly need these molecules ...

Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by DNA damage. Among the most dangerous lesions are DNA interstrand crosslinks ...

DNA repair proteins act like the body's editors, constantly finding and reversing damage to our genetic code. Researchers have long struggled to understand how cancer cells hijack one of these ...

In a way, sequencing DNA is very simple: There's a molecule, you look at it, and you write down what you find. You'd think it would be easy—and, for any one letter in the sequence, it is. The problem ...

A representative figure showing that HELQ-deficient cells fail to undergo normal fork slowing after MMC (a crosslinking agent) treatment, consistent with defective fork reversal. Every time a cell ...
