The “DNA corrector” is more efficient in the most important regions of the genome

A study published by IRB Barcelona in Nature Genetics demonstrates that the error (mutation) surveillance and repair system shows greater efficiency in the protein-coding regions of genes.

Errors made by 'DNA spellchecker’ revealed as important cause of cancer

Fran Supek (IRB Barcelona) and Ben Lehner (CRG) identify important processes that create mutations that cause cancer by studying the genomes of more than 1,000 tumors.

Many mutations in human cancers are caused by mistakes made by a repair mechanism or ‘DNA spellchecker’ rather than the actual damage to DNA caused by the environment.

Sunlight and alcohol consumption increase the rate at which this happens, resulting in more mutations in the most important parts of our genomes.
