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 ...
Researchers at the MRC Laboratory of Medical Sciences (LMS) and collaborators have uncovered one of the earliest steps in DNA replication: the moment a cell first opens its DNA to begin making a copy ...
A newly mapped step in DNA replication suggests that strand separation begins at a precise junction between two helicase ...
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 ...
Single-cell analysis helps uncover how the BK virus replicates, opening the door to new drug targets. BK polyomavirus (BKPyV) is a major cause of kidney transplant failure. Without a complete ...
