Researchers reveal an RNA modification influences thousands of genes
Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics ...

Chasing EHEC with the computer
Just a few genes make enterohaemorrhagic E. coli (EHEC) extremely dangerous to humans. If it were not for these genes, EHEC would hardly differ from harmless enteric bacteria. Bioinformatics scientists from t ...

A mystery solved: How genes are selectively silenced
Cells read only those genes which are needed at a given moment, while the others are chemically labeled and, thus, selectively turned off. Scientists at the German Cancer Research Center have now been the first to discover ...
