The Keys to a Major Process in DNA Repair

(CNRS) The DNA of our cells is continuously damaged by numerous external agents, such as carcinogens contained in tobacco smoke or UV radiation emitted by the sun. If left unrepaired, this damage leads to mutations which ultimately favor the emergence of cancerous cells, which is why the cell must rapidly and efficiently repair its DNA. To do so, the cell employs a battery of enzymes which must act in a synchronous fashion to identify and repair the damaged parts of its genome. The complexity of this process has long stumped researchers trying to understand the mechanisms at play.
Thanks to new nanotechnologies, a team of scientists which brings together both physicists and biologists has been able to film, in real-time, the enzymes that repair DNA damage…
This work will ultimately lead to new applications, both in the fight against cancer and in efforts to treat pathogenic bacteria.
