1 High blood pressure causes scarred arteries that fill up with plaque and become more prone to blood clots. 2  Sometimes plaque or a blood clot can completely close an artery, blocking the blood flow to tissue on the other side. 3  Damaged arteries cause blood supply failures. HBP causes damaged and blocked arteries. 2  A heart attack is the result of a blocked blood supply to the heart muscle tissue. 3  This can happen when the arteries to the heart become thicker and harder from a buildup of plaque.
The DNA polymerases are enzymes that create DNA molecules by assembling nucleotides, the building blocks of DNA. These enzymes are essential to DNA replication and usually work in pairs to create two identical DNA strands from a single original DNA molecule.he function of DNA polymerase is not quite perfect, with the enzyme making about one mistake for every billion base pairs copied. Error correction is a property of some, but not all, DNA polymerases. This process corrects mistakes in newly synthesized DNA.
DNA polymerase III (not DNA polymerase) is an enzyme that works in association with other enzymes during the replication of a DNA molecule. DNA replication begins when the enz â¦ yme, known as helicase unwinds a DNA strand.Helicase unwinds a DNA strand, thus, in the process, separating the two DNA templates. polymerase is an enzyme that catalyzes the conversion of free nucleotides into a single strand.   DNA polymerase differs from RNA polymerase in two major respects:   * â¦ Like all enzymes, DNA polymerase is substrate-specific.
