Although DNA is tightly packed and protected within the cell nucleus, it is constantly threatened by damage from normal ...

Every time a cell divides, it must copy its entire genome so that each daughter cell inherits a complete set of DNA. During that process, enzymes known as polymerases race along the DNA to copy its ...

DNA, though tightly packed in the nucleus, is constantly threatened by damage from metabolism and external stressors. One particularly severe form of DNA damage is the so-called DNA–protein crosslinks ...

A new study has revealed that certain locations of DNA are copied faster than others, which could also have an effect on mutation rate. Cell division is fundamental for life, allowing organisms to ...

Transposons are critical drivers of bacterial evolution that have been studied for many decades and have been the subject of Nobel Prize winning research. Now, researchers from Cornell University have ...

If severe DNA damage is not repaired, the consequences for the health of cells and tissues are dramatic. A study led by ...

E. coli divides faster than it can replicate its genome, while simultaneously expressing its genes. Scientists recently revealed the intricate molecular coordination that makes this possible. “It’s as ...

Inaccuracy of DNA replication poses novel health risk The researchers conclude that – combined with the greater radition risk in space – the inaccuracy of DNA replication under microgravity could pose ...
