Understanding methylation for beginners - (Jul/02/2013 )

I am curious to understand where exactly in the body methylation occurs, and some more basic details about it.


Methylation of DNA? If so, it occurs in the cells in the nucleus.


I did not know there was more than 1 type of methylation, and so this occurs in all cells or what?


Place where to start:


There is also methylation of RNA, done by DNMT2. So to be precise, it can be found in the nucleus and the cytosol. 

I suggest Nature Review Genetics as a good place to start
