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 ...

Maize serves as a vital model species for advancing our understanding of plant biology, yet many mysteries remain about the ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

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 ...

New research shows hydroxyurea reshapes DNA replication in cancer cells, revealing stress responses that may help design ...

From The Bedalov Lab, Human Biology and Translational Science and Therapeutics Divisions Thus, the team began this current study with a scavenger hunt for a nucleosome-modifying enzyme which could ...

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 ...
