It's a blog! Mainly of book reviews.
This is the best/most detailed description of fundamental DNA-related cellular processes I've come across. Admittedly that doesn't total to many descriptions and there is obviously an enormous amount of detailed bio-chemistry being glossed over, but it's providing an intelligible overview of what is going on. It's fascinating: how did my school teachers contrive to make biology appear boring?!
Also LEGO analogy for the win!!!
