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 ...
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, 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 ...
A new study finds that when p53, one of the most important cancer-protecting genes, stops working, cells produce too much RNA ...
A new study has uncovered a hidden step that helps the deadliest malaria parasite survive and multiply inside the human body. Researchers studying Plasmodium falciparum found that the parasite relies ...
THE precursor of life may have learned how to copy itself thanks to simple convection at the bottom of the ocean. Lab experiments reveal how DNA replication could have occurred in tiny pores around ...
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 ...
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 ...
