Our body is a complex machine, made up of the largest moving parts one could possibly imagine, and of the smallest parts that one can only see through the most advanced of microscopes. Stability and control is very important to have to make this machine work. Homeostasis is what physiologists call the relative constancy of the internal environment. The body must constantly work to maintain its stability (Patton & Thibodeau, 2008). One of the smaller parts of our complex machine is the cell. The cell is “the basic biological and structural unit of the body consisting of a nucleus surrounded by cytoplasm and enclosed by a membrane” (Patton & Thibodeau, 2008). The cell is the starting line for most of our body’s functions. Though only visible through a microscope, it plays a huge role in the functions and homeostasis of our body. DNA is found chiefly in the nuclei of complex cells, known as eucaryotic cells, or in the nucleoid regions of procaryotic cells, such as bacteria. It is often associated with proteins that help to pack it in a usable fashion (Nucleic Acids, Date unknown). Nucleic acids are a family of
