Category:Epigenetics

In terms of molecular mechanisms, the field of epigenetics has begun to florish with some recent important findings. Epigenetics as the name implies, is the inheritance mechanisms that lie outside the DNA sequence of our genes. One of the initial discoveries was the effects of DNA methylation upon gene expression and then modifications of nucleosomal histones. This DNA methylation, usually associated with 5-methylcytosine (m5C), leads to transcriptional silencing in vertebrates. Molecular mechanisms of development is an exciting area and requires a variety of different skills. This page introduces only a few examples and should give you a feel for the topic. Note that each section of system notes has a page covering molecular development in that system.
