A unique feature of HR is that it repairs the damage to the DNA in a highly accurate way. In eukaryotic cells (those with a ...

Scientists have uncovered a critical role for rapid DNA repair in maintaining genome stability. A new study reveals that ...

New research reveals that sunburn may be caused by RNA damage, not DNA, challenging long-held beliefs about UV exposure ...

Led by molecular biologist Vivian Meyer and colleagues, the team exposed two types of human skin cells — keratinocytes and ...

The efficacy of radiotherapy is largely limited by the DNA damage repair capacity of tumor cells. When ionizing radiation induces DNA double-strand breaks—the primary lethal damage—tumor cells ...

Tardigrades produce a key damage-suppressor protein known as Dsup, which binds to their DNA to protect them from radiation. Byrne and Traverso wanted to somehow arm mice with this protein so they ...

UVA (and also UVB) radiation cause indirect damage to DNA via absorption of photons by non-DNA chromophores. This generates reactive oxygen species like singlet oxygen or hydrogen peroxide that ...

radiodurans), which has the decidedly uncommon ability to survive conditions that damage DNA—for example, 5,000 to 10,000 times the radiation that would kill a regular human cell. Lead ...

Too much ultraviolet (UV) radiation from the sun can damage DNA in your skin cells and cause skin cancer. In the UK almost 9 in 10 cases of melanoma skin cancer could be prevented by staying safe in ...

Among the many dangers of excessive radiation exposure is its ability to damage DNA. In humans, the DNA damage from excessive radiation is linked to diseases including various cancers and ...

According to a new paper published in the journal Current Biology, it's not that such ionizing radiation doesn't damage tardigrades' DNA; rather, the tardigrades are able to rapidly repair any ...

Boothby Lab/Reuters Radiation is deadly because it breaks apart DNA strands. A high-energy ray that hits a DNA molecule can cause direct damage; it can also wreak havoc by colliding with another ...
