Answer: A protein domain is a region of the protein's polypeptide chain that is self-stabilizing and that folds
independently from the rest. Each domain forms a compact folded three-dimensional structure. Many proteins consist of several domains.
One domain may appear in a variety of different proteins. Molecular evolution uses domains as building blocks and these may be recombined in different arrangements to create proteins with different functions.
In general, domains vary in length from between about 50 amino acids up to 250 amino acids in length.
The shortest domains, such as zinc fingers, are stabilized by metal ions or disulfide bridges. Domains often form functional units, such as the calcium binding EF-hand domain of calmodulin.
Because they are independently stable, domains can be "swapped" by genetic engineering between one protein and another to make chimeric proteins.

The pulmonary embolism is mostly likely to have originated from the Deep veins of the leg response feedback. Pulmonary embolism occurs when a clump of material, most often a blood clot, gets wedged into artery in your lungs. These blood clots most commonly come from the deep veins of your legs. It is a blockage of an artery in the lungs by a substance that has moved from else where in the body through the bloodstream.
