There are about 6 billion nucleotide letters of a particular sequence in a human cell. The full set is known as the genome. DNA information is found in units called genes. One gene codes roughly for one protein. The proteins perform most of the functions of the body at the cellular level. Examples are digestion, the body's defense against disease, and transporting substances throughout the body. Thousands of proteins

Rheumatoid arthritis is a widespread autoimmune disease that is linked to progressive disability, socioeconomic costs, systemic complications, and even early death. In addition to having an unknown cause, the disease also has a guarded prognosis. In the past few years, there have been several attempts to understand the pathogenesis of the disease, which have resulted in the creation of new therapeutics with enhanced outcomes (McInnes & Schett, 2011, p.2205). As

In conclusion, although the anthrax bacterium is relatively low on the list of possible contaminants, future research on this potentially fatal disease should continue, particularly when considering the ever-growing threat from terrorist actions and the possibility that as the world population increases, the presence of the anthrax bacterium will also increase, due to the growth of farming, land clearing and many agricultural activities aimed at increasing the world's food supply
