Guarding genes against damage is a crucial and complex job, so it’s to be expected that cells have several mechanisms to repair DNA breakages, each providing support under different circumstances.

DNA damage and repair refers to the creation and correction of DNA lesions that threaten genome integrity. Because DNA replication errors or environmental agents that damage DNA can introduce ...

Homologous recombination plays essential roles in the repair of DNA double strand breaks (DSBs) and collapsed replication forks. The fundamental reaction in homologous recombination is the exchange of ...

we were helping to assist in the assembly of DNA molecules by using the electronic methods," Heller says. It was the beginning of assisted self-assembly of individual DNA molecules. Nanogen's most ...

The genetic connections between DNA repair pathways and human cancer predisposition have fueled interest in the proteins that recognize and repair specific sites of DNA damage. The repair enzymes are ...

On the other hand, animals — including humans — self-replicate all the time using DNA. Now, scientists are making tiny nanorobots from DNA that can assemble more DNA, including copies of ...

"The surprising result of our research is that DNA repair, which normally protects healthy cells, determines how cancer cells die following radiotherapy," said Prof Cesare. "The DNA inside our ...

A study, which was published in the journal Occupational & Environmental Medicine, found that melatonin seems to help actually some people repair DNA damage while sleeping. As you may know ...
