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.
Key Concepts: Bacterial DNA polymerase I enzymes are multidomain proteins with separate polymerisation, proofreading and 5â²â3â² exonuclease functions. They perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.Polymerases incorporate one nucleotide at a time to the 3â² end of the primer DNA strand in a templateâdirected manner.hey perform a vital function in bacteria by carrying out DNA repair and some aspects of chromosomal replication.
