Red Blood Cells -- Mitochondria, Nucleus, Atp

I was watching Law and Order one sleaziness and the topic was falsifying DNA evidence. During the show they mentioned that cherry- deprivation bloodline cells do not nurse mitochondria or nuclei. The bad guys took allowance 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 loss to frame. I was very surprised by the accuracy of this scenario! This is a re wholey cool thing roughly red line of descent cells, because when we talk about eukaryotic cells we say they have a core group and other complex organelles -- like mitochondria, just now red assembly line cells are different. The main turn 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 degree Celsius dioxide. It carries oxygen to cells that rent it and picks up the carbon dioxide that is a violent product of aerophil ous respiration and returns that to the lungs to be exhaled. In enunciate for this process to be very efficient, red blood cells have no pith -- it would take up too frequently room. You should hence ask, since the nucleus contains the DNA and this is required for cell course of study 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 hug cells.

Bone marrow cells grow and divide. When the bone marrow cells progress they become all of the different types of blood cells. As a red blood cell matu res, it loses its nucleus. No nucleus, no DN! A, 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(prenominal) hemoglobin if there is no DNA to enounce them how. They do not do that either. approximately 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. bring forward about it.
