The first place to look for a leak in a modern car is the fuel tank vent hose or the fuel injection line. Older cars, pre-1980âs, have a carburetor float bowl. When you shut off a pre-1980 car there is normally some boiled fuel that will create a smell of gas.
PROTHROMBIN GENE MUTATION Prothrombin gene mutation is the second most common cause of inherited thrombophilia in the United States. It is present in about 2% of Caucasians. It is caused by a cha nge or mutation in the gene for the blood clotting protein called prothrombin (which is also called Factor II).People with the prothrombin gene mutation have higher than normal levels of prothrombin in their blood, making them prone to blood clots, most common in the veins.t is caused by a cha nge or mutation in the gene for the blood clotting protein called prothrombin (which is also called Factor II).

Gene mutation is the change in the DNA sequence that is permanent  and leads to new genetic traits and even diseases. This type of  mutation is triggered through hereditary â¦ process or through several  factors in the environment. permanent change in the gene's DNA sequence. Gene mutations involving one or a few nuckeotides is called point mutation. If a nucleotide is added or deleted, the bases are s â¦ till read in groups of three, but now those groupings are shifted for every codon that follows. This is called frameshift mutation.
