Epigenetic differences arise during the lifetime of monozygotic twins. – FPrime
Epigenetic differences arise during the lifetime of monozygotic twins.? Unsurprisingly, older twin pairs differed more in things like DNA methylation and histone acetylation than younger twins.

Image of the Day: You are a close professional associate of any of the authors e. We found that, although twins are epigenetically indistinguishable during the early years of ywins, older monozygous twins exhibited remarkable differences in their overall content and genomic distribution of 5-methylcytosine DNA and histone acetylation, affecting their gene-expression portrait. By comparing the epigenomes of both twins, we can isolate genes that contribute to the development of these diseases.? Recommend to your librarian.
