<h1> Epigenetics</h1>
<hr />
<h2>Definition : Heritable changes in gene activity and expression that occur without alteration in DNA sequence</h2>
<hr />
<h2>Epigenetic modifications are crucial for packaging and interpreting the genome</h2>
<hr />
<h2>Two well-known epigenetic modifications</h2>
<ol>
<li>Chemical modification to the cytosine residues of DNA (DNA methylation)</li>
<li>Histone modification</li>
</ol>
<h3>The patterns of epigenetic modifications can serve as</h3>
<ol>
<li>Epigenetic markers to represent gene activity and expression</li>
<li>Epigenetic markers to represent chromatin state</li>
</ol>
