EPIGENETIC MEMORY

I have been studying the field of epigenetics for about ten years or so now? Something like that. Since the field of genetics has been a personal interest of mine for decades. But I only relatively recently became of aware of modern epigenetics and began studying it in depth.

I see it as being directly related (as a manipulation mechanism) to my theory of the Renaissance Man and the polymath.

Anyway I thought this was a rather good but very basic summary of some of the recent research advances and studies in the field.

Study shows how epigenetic memory is passed across generations
This image shows inheritance and transmission of the epigenetic mark H3K27me3 in C. elegans. The 1-cell embryo (left) shows the mark (green) inherited on sperm chromosomes but not on the oocyte chromosomes (pink) contributed by a mutant mother lacking the methylation enzyme PRC2. The 2-cell embryo (right) shows transmission of the mark on the sperm-derived chromosomes in each daughter nucleus. Credit: Laura J. Gaydos
A growing body of evidence suggests that environmental stresses can cause changes in gene expression that are transmitted from parents to their offspring, making "epigenetics" a hot topic. Epigenetic modifications do not affect the DNA sequence of genes, but change how the DNA is packaged and how genes are expressed. Now, a study by scientists at the University of California, Santa Cruz, shows how epigenetic memory can be passed across generations and from cell to cell during development...
