A branch of science that attempts to understand the fundamental biologic makeup of organisms by examining the genetic blueprints in each cell

The nucleus of every cell holds the key to nearly every visible and invisible feature of the human body, from the color of hair to the pumping capacity of the heart. In each nucleus of every cell there are 23 pair of chromosomes (46 total). One pair of these chromosomes determines the sex of the child while the other 22 pair determine all the other components of the human body. Chromosomes contain genes which influence the production of proteins and thus influence all aspects of body structure and function. There is a tremendous amount of information encoded in the nearly 100,000 genes in each cell Geneticists and molecular biologists work to identify the variations that exist between animals or humans by studying the changes...
