Locations. DNA is found in the nucleus and mitochondria of the cell. RNA begins its existence in the nucleus, but may move to the cytoplasm to complete its mission. Mitochondria live within the cytoplasm of the cell, which is the part between the cell nucleus and the cell wall.ocations. DNA is found in the nucleus and mitochondria of the cell.

Exercise has a number of effects that benefit the heart and circulation (blood flow throughout the body). These benefits include improving cholesterol and fat levels, reducing inflammation in the arteries, helping weight loss programs, and helping to keep blood vessels flexible and open.
The effect of exercise on pulse and breathing rate. Exercise increases the rate at which energy is needed from food. This increases the need for both food and oxygen in the body. This is why your pulse rate and breathing rate increase with exercise. Your pulse is just an indication of your heart rate as your arteries expand each timethe ventricles pump blood out of the heart. Your heart speeds up to pump extra food and oxygen to the muscles.
