Introduction to Epigeneitcs Science
What is epigenetics?
The term epigenetic is often used to describe a variety of unexpected patterns of gene regulation.
Chemical modifications of chromosomal DNA and/or structures that change the pattern of gene expression without altering the DNA sequence.http://en.waleedabobatta.com/2018/03/28/introduction-to-epigenetics-science/
The epigenome consists of the chemical compounds that tell DNA what to do, where to do it and when to do it,
All of which can be functions undertaken by any one of organism cells using the same identical DNA toolkit.
e.g. grow a finger vs. grow a nose, grow cancer vs fight cancer.in other words, if DNA is hardware and epigenome as the software that controls hardware.
