Anybody interested in exploring the Nature vs. I would strongly encourage anybody with an interest in biochemistry or biology to read this book as it provides a detailed, yet accessible, insight into the revolutionary new discipline of Epigenetics. Approximately 98 percent of the DNA in the human genome is non-coding (exons), which means that it does not encode a protein, however this does not mean that it has no function. These differences are a matter of changes to gene expression as a result of some environmental impact. How can this be possible if their genetic code is exactly the same? An example, given by Carey, is seen in caterpillars which later develop into butterflies, with no change in their DNA sequence. I had no idea what Epigenetics was before reading this book but after getting just a couple of pages in I couldn’t believe how much I had been missing out on!Įpigenetics is the study of differences between genetically identical organisms which have non-identical phenotypes. The Epigenetics Revolution by Nessa Carey is a book that was recommended to me during my Biochemistry interview at Univ, so I read it over the summer after my A Levels.
