DNA can sustain serious injuries called double strand breaks, in which both strands of the helix snap. These breaks are among the most dangerous forms of DNA damage and immediately trigger the cell's ...

Cancer research, drug safety testing and aging biology may all gain a major boost from a new fluorescent sensor developed at Utrecht University. This new tool allows scientists to watch DNA damage and ...

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 ...

For almost 60 years, scientists have tried to understand why DNA doesn't replicate wildly and uncontrollably every time a ...

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 ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible ...
