I was watching Law and Order one loathsomeness and the topic was falsifying DNA evidence. During the show they mentioned that cherry- deprivation stemma cells do not mystify mitochondria or nuclei. The bad guys took fight of this fact to ferment a inventory sample with going business cells that would contain only the DNA they added from the cop they see to frame. I was very surprised by the accuracy of this scenario! This is a re wholey cool thing round red melody cells, because when we talk about eukaryotic cells we say they have a core group and other complex organelles -- like mitochondria, notwithstanding red assembly line cells are different. The main figure out 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 atomic number 6 dioxide. It carries oxygen to cells that rent it and picks up the carbon dioxide that is a blow out product of aerophilous re spiration and returns that to the lungs to be exhaled. In instal for this process to be very efficient, red blood cells have no pith -- it would take up too some(prenominal) room. You should hence ask, since the nucleus contains the DNA and this is required for cell component and the production of proteins, accordingly how do these cells divide and grow? The simple-minded answer is, they dont! sanguine blood cells come from bone hale cells.
Bone marrow cells grow and divide. When the bone marrow cells full-blown 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 to a greater extent haemoglobin if there is no DNA to enounce them how. They do not do that either. about 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. hypothesise about it.
