Blood Clotting
When blood vessels are cut or damaged, the loss of blood from the system must be stopped before shock and possible death occur. This is accomplished by solidification of the blood, a process called coagulation or clotting.
Blood clotting
If blood vessels are damaged a series (cascade) of enzyme-control reactions occurs to form a clot

Serum albumin
Blood clotting factors (to facilitate coagulation)
Immunoglobulins (antibodies)
Various other proteins
Various electrolytes (mainly sodium and chloride) ...
An X-linked recessive genetic disease, caused by a mutation in the gene for clotting factor VIII (hemophilia A) or clotting factor IX (hemophilia B), which leads to abnormal blood clotting. Herbicide.
Chemicals responsible for blood clotting are synthesized in the liver, as is albumin, the major protein in blood. The liver also makes or modifies bile components.
So the hemophilia gene was identified by knowing there was a problem with a blood clotting factor and then figuring out what gene must have coded for that, and isolating or cloning that gene.
(Cancer is caused by mutations in our body cells.) Vitamin K helps in blood clotting.
Every human cell (except for red blood cells and the platelets that are critical to normal blood clotting and wound healing) contains a discrete nucleus that has within the roughly 6 feet of a special chemical called deoxyribonucleic acid, or DNA.
They carry chemicals essential to blood clotting. Platelets survive for 10 days before being removed by the liver and spleen. There are 150,000 to 300,000 platelets in each milliliter of blood.
(Science: haematology) blood clotting factors, especially from humans. These factors form a cascade in which the activation of the first factor leads to enzymic attack on the next factor and so on, finally resulting in blood clotting.
For example, one species that lives symbiotically in the large intestine manufactures vitamin K, an essential blood clotting factor. Other species are beneficial indirectly. Bacteria give yogurt its tangy flavor and sourdough bread its sour taste.
