Genomic functions take place in chromatin, not in naked DNA.
An international team led by computational biologist Fran Supek at IRB Barcelona develop a machine learning method to predict unknown gene functions of microbes.
The system examines and compares ‘big data’ available on the metagenomes of human and environmental microbiomes.
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.
