Epigenetic modifications meaning
WebEpigenetics is the study of heritable changes in genome function that are not associated with DNA sequence alterations. Such changes occur in all kingdoms of life. In bacteria, DNA methylation plays a role in the formation of cell lineages. In eukaryotes, multiple mechanisms of chromatin modification permit mitotic and/or meiotic transmission ...

The term epigenetics in its contemporary usage emerged in the 1990s, but for some years has been used with somewhat variable meanings. A definition of the concept of epigenetic trait as a "stably heritable phenotype resulting from changes in a chromosome without alterations in the DNA sequence" was formulated at a Cold Spring Harbor meeting in 2008, although alternate definitions that include non-heritable traits are still being used widely. making butter with cannabis leavesWebEpigenetic change is a regular and natural occurrence but can also be influenced by several factors including age, the environment/lifestyle, and disease state.
