What is Epigenetics?

Epigenetics is the study of a group of mechanisms that cells use to turn genes on or off, or to turn a gene’s activity (also called gene expression) up or down. There is also an element to these mechanisms that involves a memory of how a cell’s parent, grandparent or even further back has expressed these genes. One popular analogy for the interplay between genetics and epigenetics is to think of the human body as a computer. DNA is the hard drive and the epigenetics is the software which is driving the computer. The software tells the hard drive which tasks to perform and when but without the hard drive the software would have nothing to run on.

Chromatin remodeling
If you have ever seen a cell under a microscope, you may remember seeing the big X structures called chromosomes—humans have 23 pairs. Popular image of these chromosomes may lead you think to our genetic…
DNA Methylation
Humans have 19,000 genes spread over 23 pairs of chromosomes and need all of those genes working in synchrony to make you—you. But not every cell needs to express every one of those genes. Your…
Histone modifications
The structure of DNA is a double helix, something many of us will remember from our high school biology class, a discovery made by Watson and Crick by borrowing data from others (like Rosalind Franklin).…
Non-coding RNA
The central dogma of biology states that the genetic information is hard-wired into DNA which is transcribed into individual transportable cassettes, composed of messenger RNA and each mRNA cassette contains the program for the synthesis…
