SECTION 2
THE MOLECULAR BIOLOGY OF THE CELL
The central dogma of molecular biology is “DNA makes RNA makes protein.” That central concept defines the structure of this section of the book, which moves from DNA through RNA to the synthesis of proteins. Single‐celled organisms change their behavior by altering the spectrum of RNAs and proteins that they make, while the cells of an animal or plant differentiate into different cell types by selecting different RNAs and proteins to synthesize. We will therefore describe the control mechanisms that operate to allow selective synthesis and readout of RNA. We will describe the ribosome, the machine for making protein using the instructions on DNA, and then describe the many and varied structures and behaviors of proteins. Lastly, in Chapter 8, we will describe some of the techniques that have made molecular biology such a powerful technology for both manipulating and investigating cells and organisms.
