Accurate DNA replication is essential for genome maintenance. Two recent reports have uncovered new molecular mechanisms controlling the termination phase of DNA replication in higher eukaryotes and ...
Scientists look at the base pairs that compose the "rungs" of the DNA ladder to determine a genome's sequence. The success of E. coli bacteria depends on their ability to multiply very rapidly by ...
DNA replication is essential to all life, yet many basic mechanisms in that process remain unknown to scientists. The structure of the replisome--a block of proteins responsible for unwinding the DNA ...
A series of electron micrographs show the barrel-shaped helicase with several components of the replisome: a) helicase (grey) with Ctf4 (light blue), which is a recruitment factor for the ...
What happens to DNA replication when its components compete with other processes for access to the genome? Purified surface immobilized single GFP molecules on a slide (1). DNA replication is often ...
Single-molecule imaging techniques have enabled researchers to reveal the workings of the replisome, the molecular machinery that replicates DNA. A team including researchers from the University of ...
Reactive oxygen species (ROS) were long regarded as harmful by-products of mitochondrial metabolism, but growing evidence—including our own—shows that ROS also signal to core processes such as ...
