The Central Dogma. This hypothesis was described by Crick in 1958. In 1953‚ Watson and Crick were the first to determine the true crystalline structure of DNA‚ using model building and then X-ray crystallography. Once the DNA structure was determined‚ the mechanisms behind inheritance‚ information flow‚ and gene function fell into place. Overall the flow of information is depicted as: DNA --> RNA --> protein. Both DNA and RNA can be replicated (i.e. DNA is synthesized from DNA‚ and RNA from RNA)

Coronary Artery Disease‚ also known as Coronary Heart Disease‚ is the most common heart disease. In both men and women‚ it is the leading cause of death in the United States. Coronary arteries carry blood to the heart. CAD is caused by a thickening of these arteries‚ called atherosclerosis. Plaque‚ a substance containing cholesterol and other fatty substances‚ builds up inside the thickened walls of the arteries‚ which slows or blocks blood flow to the heart. In result‚ the heart cannot receive the

1. Procedure Coronary Artery Bypass Graft (CABG) is performed when a patient has disease of the coronary arteries. This is usually caused by atherosclerosis which is clogging of the arteries or hardening by cholesterol of plaque. Coronary Artery Bypass is done to improve the blood flow of the heart.

One of the most common forms of heart disease in the United States is coronary artery disease (CAD)‚ leading to hundreds of tragic deaths each year. Coronary artery disease arises when the coronary arteries in the heart become narrowed or blocked. Anyone can develop this disease‚ but it typically occurs later in life and it is more common in men. CAD ultimately arises from plaque and cholesterol clogging the arteries‚ blocking blood flow. This can lead to symptoms of angina (chest pain)‚ dyspnea
