Chapter 8
How Genes Work
       |
In chapter 3 the site of protein synthesis was reveled. It is the ribosome. In chapter 7 the text describes the process by which traits are inherited from parents, by the offspring. Mendel discovered that the inheritance of these traits follows a predicatble pattern. In chapter 8 it is shown that traits are actually expressions of genes in the form of proteins. Genes found on DNA hold the codes for proteins that will be produced at the site of the ribosome. In all organisms DNA codes for proteins. This is another example in continuity among organisms and is the central dogma of biology. DNA codes for proteins which are used to make us who we are. |
