This is a very good resource. It's basically a very complete, detailed and up to date online biology textbook. It consists of hundreds of extensively hyperlinked webpages on all aspects of advanced-introductory biology. (A first course weighted towards cell and molecular biology for biology majors.) If you follow the links, it provides far more detail than normal textbooks and its easy to pursue your curiosity and interests. (I just found out about nucleomorphs.)
The author is a retired Harvard professor who once taught high-school, the information is authoritative and the writing style is extraordinarily clear and easy to understand (the high-school teaching influence). All the relentless jargon of molecular biology is clearly explained. (It's just a fact of life [literally] that what is happening inside each of your billion+ cells is hugely complicated and the various objects, processes and events all have names.)
A good place to dive into it is the index page.
