Rethinking the Genetic Theory of Inheritance
Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for ...

Gene switch sites found mainly on 'shores,' not just 'islands' of the human genome
Scientists who study how human chemistry can permanently turn off genes have typically focused on small islands of DNA believed to contain most of the chemical alterations involved in those switches. But after an epic tour ...

In lung cancer, silencing one crucial gene disrupts normal functioning of genome
While examining patterns of DNA modification in lung cancer, a team of international researchers has discovered what they say is a surprising new mechanism. They say that "silencing" of a single gene in lung cancer led to ...
