What causes the difference between the mRNA molecule in different tissue is PRE mRNA SPLICING. Splicing refers to the modification of the nascent precursor messenger RNA.The splicing of a mRNA molecule occur in several steps and the steps are catalyzed by ribonucleoproteins. During splicing, the introns sections are removed and the remain sections called exons are joined together.

The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori,[1] refers to the metabolic pathway in which lactate produced by anaerobic glycolysis in the muscles moves to the liver and is converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.[2]
