RBC's die because they eject their nucleus during their formation in order to make more room for hemoglobin. Without a nucleus they are unable to make repairs and due to the stresses of traveling within the cardiovascular system. As a result they last on average about 120 days.
Worn out RBC's are removed from circulation in the spleen and liver. The heme and globin portions of hemoglobin are split apart. The globin is broken down into amino acids which can be used to synthesize other proteins. Iron is removed from the heme portion and used to synthesize new heme molecules. The non-heme portion goes through a series of chemical transformations and eventually ends up as something called sterocobilin which is what gives feces it's characteristic brown color.

Does mature RBCs rely on anaerobic glycolysis?
Yes. Mature RBCs lack the necessary organelles to perform any other processes besides glycolysis. They rely on anaerobic glycolysis for energy.
How are red blood cells recycled?
Eventually the RBCs are unable to spring back into shape as they pass through capillaries and this lack of flexibility traps old RBCs in the spleen. The damaged RBCs are phagocytosed by macrophages, the proteins are hydrolyzed, iron is concentrated in transferrin and the chemical frame of the heme structure is partially disassembled and ultimately eliminated as part of the bile used in digestion. Millions of RBCs are born and recycled each day to maintain a constant level of oxygen in tissues .
What is the relationship between rapid rate of RBC destruction and jaundice?
The destruction of RBCs results in the release of bilirubin. If excessive amounts of RBCs are destroyed it creates a build up of bilirubin in the blood which leads to jaundice.

We can not extract DNA from RBCs as they are without nucleus. only the source of DNA extraction is Leukocytes, RBCs are not good source of extraction but we can extract DNA from immature RBCs.
