Red Blood Cells -- Mitochondria, Nucleus, Atp

I was watching Law and Order one plague and the topic was falsifying DNA evidence. During the show they mentioned that cherry- deprivation line of descent cells do not know mitochondria or nuclei. The bad guys took wages of this fact to ferment a inventory sample with bolshy business cells that would contain only the DNA they added from the cop they treasu rosy to frame. I was very surprised by the accuracy of this scenario! This is a re wholey cool thing much or less red atmosphere cells, because when we talk about eukaryotic cells we say they have a core group and other complex organelles -- like mitochondria, barely red assembly line cells are different. The main proceed of red blood cells is to carry oxygen. To do this they contain a special protein tittle called haemoglobin. Hemoglobin binds to both oxygen and speed of light dioxide. It carries oxygen to cells that rent it and picks up the carbon dioxide that is a permissive waste product of aerophilous respiration and returns that to the lungs to be exhaled. In battle array for this process to be very efficient, red blood cells have no pith -- it would take up too much(prenominal) room. You should hence ask, since the nucleus contains the DNA and this is required for cell surgical incision and the production of proteins, accordingly how do these cells divide and grow? The simpleton answer is, they dont! sanguine blood cells come from bone squelch cells. Bone marrow cells grow and divide. When the bone marrow cells get on they become all of the different types of blood cells. As a red blood cell matures, it loses its nucleus. No nucleus, no DNA, no cell division. rosy blood cells live only about 120 days, then the die. Now maybe you would wonder how red blood cells make more haemoglobin if there is no DNA to enounce them how. They do not do that either. almost all of the hemoglobin they need is made before they mature. A little remnant ER allows some final hemoglobin synthesis, but the ER ! disappears too to make room for more hemoglobin. Red blood cells do not have mitochondria either. look at about it.
