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

Top: Chromosome separate with functioning SMC in two models, line drawing and filled-space. The red and pink dots indicate, respectively, ori on each copy of DNA. Bottom: DNA separating without ...

DNA replication is happening continuously throughout the body, as many as trillions of times per day. Whenever a cell divides—whether to repair damaged tissue, replace old cells, or simply to help the ...

When bacteria cells replicate, they do so a little differently than human cells do. They don't undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Researchers at the Center for Embryology and Healthy Development (CRESCO) aim to find out why so many early embryos fail in their development. New insights into how maternal and paternal DNA is ...

When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...

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-folding nanorobots can manufacture limitless copies of themselves By Loz Blain December 08, 2023 Tiny nano-robots have been developed that can grab tiny snippets of DNA and assemble them into new ...
