Cell biology encompasses everything about cells from its basic structure to the functions of every cell organelle a single cell is an organism in itself such as yeast or bacterium other cells gain special functions soon after they mature. Chapter 1: cells and tissues describe the basic structure of a eukaryote membrane compare the the cell biology of the immune system. A cell is a dynamic and a complex structure surrounded by a membrane known as the plasma membrane this acts like a barrier between the inside of the cell and the outside resulting in different chemical environments on the two sides the cell membrane is not restricted to the outer surface but is. The goal of this course is to teach both the fundamentals of nuclear cell biology as well as the methodological and experimental approaches upon which they are based lectures and class discussions will cover the background and fundamental findings in a particular area of nuclear cell biology.
