In this reaction, all reactants and products are invisible. The heat being evolved is the clue that tells you a reaction is taking place. This is a good example of an exothermic reaction, a reaction in which heat is given off. A lot of reactions are exothermic.
Prothrombinase will cleave prothrombin to make thrombin and thrombin is the enzyme that cuts fibrinogen to make fibrin for clot formation [Blood Clotting: The Basics]. The platelet prothrombinase activity is the same as the activity on TP-bearing cells: itâs formed from Xa and membrane-bound Va.
Best Answer: (1)The primary role is to add the A's, C's, T's and G's to the elongating new strands of DNA. (polymerization of dNTP's) (2) However, it also proofreads the new copies, (3) AND changes the RNA primers used to initiate replication into DNA.(short single stranded RNA primers find the start points of DNA replication, but they need to be converted into DNA before the pieces can be ligated together.NA polymerase is used to bring in the correct nucleotides when DNA is in the process of replication. It also proofreads the double helix once the new DNA is made. Rose Â· 7 years ago. Thumbs up. 1. Thumbs down. 0. Comment. Add a comment. Submit.
