A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life reconstructions ever created. Using computer technology, scientists have ...

By simulating the life cycle of a minimal bacterial cell—from DNA replication to protein translation to metabolism and cell ...

A giant DNA virus pulled from a Japanese freshwater pond is forcing scientists to rethink how complex cells first acquired their defining feature: the nucleus. Named ushikuvirus, the newly ...

A fleeting DNA fold called i‑DNA can switch cancer‑related genes on and off, revealing a hidden structural weak point that ...

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 ...

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 ...

A protein that is involved in determining which enzymes cut or unwind DNA during the replication process has been identified. A protein that is involved in determining which enzymes cut or unwind DNA ...

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 ...

Biology lectures teach students that when a cell’s replication machinery comes together, DNA polymerase takes off down the double-helix like a car on a highway ...
