DNA methylation is the covalent addition of methyl groups to DNA bases, typically the cytosine of CpG dinucleotides. It is catalyzed by methyltransferase enzymes using a S-adenosyl methionine ...

Recently, Professor Frédéric Veyrier at the Institut national de la recherche scientifique (INRS) and his team developed a new genetic tool based on a family of specific enzymes called Ssn that allows ...

This study provides valuable findings on the role of site-specific DNA methylation changes during spermatogenesis and their contribution to paternal epigenetic inheritance. The study proposes that ...
