Researchers at the University of Toronto have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and ...

Researchers have discovered a DNA repair mechanism that advances understanding of how human cells stay healthy, and which could lead to new treatments for cancer and premature aging. Researchers at ...

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, ...

When an SSB appears, polymerase epsilon approaches the nick before retracing its steps thanks to its exonuclease, allowing fork reversal to take place. The nick is repaired as an SSB, and replication ...

Researchers from Tokyo Metropolitan University have identified key factors in the mechanism behind DNA repair in our bodies. For the first time, they showed that the "proofreading" portion of the DNA ...

Researchers decode repair mechanism during transcription of genetic information. Cockayne syndrome is a severe autosomal recessive disorder caused by defective DNA repair mechanisms. People with the ...

Homologous recombination is a DNA repair mechanism that counteracts double-stranded breaks in DNA. Researchers at Kindai University have recently revealed how the Sae2 protein coordinates with the ...

The human genome is contained within the nucleus of cells. The genome is well protected, but many things can cause DNA damage, including aging, some drugs, and environmental factors like UV rays or ...

A major advance in cell biology has revealed how our cells safeguard their genetic material during one of the most vulnerable moments in their life cycle. The study identifies a specific protein ...

Not all DNA looks like the familiar double helix. Sometimes, parts of our genetic code fold into unusual shapes under certain conditions. One such structure known as a G-quadruplex (G4) looks like a ...
