Question 2

What is epigenetics and how does it work?

Dr. Morgan Healy · Accepted Answer

Epigenetics – It's not just genes that make us. Quick look: In its modern sense, epigenetics is the term used to describe inheritance by mechanisms other than through the DNA sequence of genes. ... It works through chemical tags added to chromosomes that in effect switch genes on or off.

Question 3

What is epigenetics in biology?

Dr. Morgan Healy · Accepted Answer

Epigenetics is the study of heritable changes in gene expression (active versus inactive genes) that do not involve changes to the underlying DNA sequence — a change in phenotype without a change in genotype — which in turn affects how cells read the genes.

Question 4

Why is epigenetics so important?

Dr. Morgan Healy · Accepted Answer

The significant role of epigenetics in brain development and disease is due to the following factors: 1) plasticity of epigenetics during all periods of brain development and aging as well as dynamic regulation in neurons, 2) disordered chromatin organization in both early childhood and adult neurodegenerative ...

Dr. Morgan Healy · Answer

Robin Holliday defined epigenetics as "the study of the mechanisms of temporal and spatial control of gene activity during the development of complex organisms." Thus epigenetic can be used to describe anything other than DNA sequence that influences the development of an organism.

Question 6

Can Epigenetics be reversed?

Dr. Morgan Healy · Accepted Answer

The term has evolved to include any process that alters gene activity without changing the DNA sequence, and leads to modifications that can be transmitted to daughter cells (although experiments show that some epigenetic changes can be reversed). ... Another significant epigenetic process is chromatin modification.
