WHY STUDY CELLS & ITS COMPONENTS 2 The cell is the most basic building block of all living organisms as we know it. In fact, the study of genetics and the study of cells are closely related. The process of passing on genetics from one generation to another depends on how cells grow and divide. In order to reproduce, a living organism, such as bacteria, will replica its DNA by splitting in two, a process called binary fission. Instead, the organisms that reproduce sexually mix and match strands of DNA, a process called recombination. Thus it reduces the amount of DNA in special sex cells to arrive at completely new genetic combinations for their offspring. Both of these processes are what make each and everyone of us unique. Each of us needs to understand mitosis (cell division) and meiosis (the production of sex cells) to appreciate how genetics works. There are two types of organisms, prokaryotes and eukaryotes. Prokaryotes are cells that do not possess nucleus and Eukaryotes are cells that have nucleus which protects the DNA. Prokaryotes are the most common forms of life on earth and every moment we are all covered in millions of prokaryotic cells, or bacteria. Our life depends on the bacteria, for example, in our bodies digestion going on in our intestines is partially powered by bacteria which break down the
