DNA is the same in every cell throughout an individual's body, whether it is a skin cell, sperm cell, or blood cell. With the exception of identical twins, no two individuals have the same DNA blueprint.
Red Blood Cells (RBCs) make up approximately 40% of Blood volume, carry oxygen to the cells of your body and return to the lungs to excrete carbon dioxide. Platelets, the smallest of the Blood cells; make up 5% to 7% of total Blood volume.Platelets form a 'mesh' net to form clots in the Blood to help stop bleeding.ed Blood Cells (RBCs) make up approximately 40% of Blood volume, carry oxygen to the cells of your body and return to the lungs to excrete carbon dioxide.

The percentage of whole blood volume that is made up of red blood cells is called the hematocrit and is a common measure of red blood cell levels. back to top White Blood Cells (also called leukocytes) White blood cells protect the body from infection. They are much fewer in number than red blood cells, accounting for about 1 percent of your blood. The most common type of white blood cell is the neutrophil, which is the immediate response cell and accounts for 55 to 70 percent of the total white blood cell count. Each neutrophil lives less than a day, so your bone marrow must constantly make new neutrophils to maintain protection against infection.
