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

New research sheds light on how cells repair damaged DNA. For the first time, the team has mapped the activity of repair proteins in individual human cells. The study demonstrates how these proteins ...

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 ...

An estimated 105-106 DNA lesions are generated in the human genome daily. The human genome is constantly being assaulted by various sources of DNA damage, which threaten DNA stability and integrity.

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

A novel technology combined with optical tweezer C-trap technology gives researchers new insight into DNA repair mechanisms. Researchers at the University of Pittsburgh (PA, USA) have developed a ...

DNA repair is essential for the maintenance of genomic stability and its failure can lead to human disease. Various DNA repair systems exist, such as base excision repair, nucleotide excision repair, ...

Combining an optical tweezer technology called C-trap that manipulates a single molecule of DNA and a novel approach, researchers were able to receive a detailed view into how cells find and repair ...

DNA is well known as the blueprint of life, necessary for an organism to facilitate living processes. DNA can be damaged by various factors such as radical metabolites, radiation, and some toxic ...

DNA is often described as the instruction manual for building the fundamental components of life. Proteins are helpers that ...

A new study shows that cancer damages its own DNA by pushing key genes to work too hard. Researchers found that the most ...
