👉 Epigenetics is a branch of biology that studies the heritable inheritance and regulation of gene expression without altering the DNA sequence. It focuses on understanding how genes are passed down through generations, rather than changing their genetic code directly. In epigenetics, changes in gene expression occur without altering the specific nucleotide bases within the DNA sequence itself. These changes can be inherited from parents and may also involve environmental factors such as diet, stress levels, or certain chemicals. Epigenetic modifications are not permanent
