Cell biology has become more popular that last few years with various types of infections being in the news. Cells of almost any kind have a basic anatomy and if you know the parts of the cell, you will have a much better understanding of what the news is talking about. I go over DNA and RNA, and introduce to you the concept of epigenetics. That is the expression of this DNA.

All of the cells with a nucleus in your body has the same DNA, yet they have vastly different functions. This is epigenetics.
