Scientists Show Transmission of Epigenetic Memory Across Multiple Generations

Posted by in categories: biotech/medical, genetics

Changing the epigenetic marks on chromosomes results in altered gene expression in offspring and in grandoffspring, demonstrating ‘transgenerational epigenetic inheritance.’

Without changing the genetic code in the DNA

DNA, or deoxyribonucleic acid, is a molecule composed of two long strands of nucleotides that coil around each other to form a double helix. It is the hereditary material in humans and almost all other organisms that carries genetic instructions for development, functioning, growth, and reproduction. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
