Epigenetic changes are those which do not involve alterations in the DNA sequence. These are caused due to interaction of the genome with the environment.
When are alterations epigenetic?
- Epigenetic modifications or tags include DNA methylation and histone modification.
- These changes alter DNA accessibility and chromatin structure thus regulating gene expression.
- These are the reversible, heritable changes which do not change your DNA sequence, but they can change how your body reads a DNA sequence.
- These are necessary for the normal development of organisms.
- Stable, long-term epigenetic modifications involve DNA methylation.
- Flexible, short-term changes involve histone modifications, such as methylation and acetylation.
