Recently, a lot of attention has gone to epigenetics, or heritable changes in gene expression caused by mechanisms other than changes in DNA sequence. An example of such a mechanism is DNA methylation, where a methyl group (CH3) binds to cytosine or adenine. Epigenetic changes might explain the discrepancies that are being discovered between what the genetic code dictates and how an organism actually looks and functions, ranging from flower shape to the tendency for obesity. read more
