Transcript of Epigenetics

Epigenetics
"study of heritable changes in gene expression that are not due to changes in DNA sequence"
Definition:
The addition of a molecule to the histone.
e.g:
methylation
acetylation
sumoylation
ubiquitylation
phosphorylation
Histone Modification
Environmental Influences
Identical Twins

DNA Methylation
(Eccleston et al, 2007)
Many system and mechanisms including but not limited to:
DNA methylation
Histone modification
Nucleosome location
Noncoding RNA

Epigenetic tags act as a non-genetic cellular memory.

Leads to the specialisation of cells

Remains flexible
