DNA replication

DNA is the same from uncoiling spirals, break Strand separation of hydrogen bonds between complementary strands, as the synthesis of two new strands by additional base pairing. Origin of replication begins in a special place in DNA is called replication. DNA replication origin of bidirectional replication. To begin replication of DNA unwinding enzymes called DNA helicases causes two strands of DNA to relax and parents separated from each other at the beginning of replication to form two Y "-shaped" forks repetition. These replication forks are the right place to DNA copying. Helix destabilizing protein related to a stranded regions, so that two strands are not refundable. Topoisimerases produce enzymes called DNA breaks in, and then rejoin them in order to ease tension in the helical molecule during replication. As topics continue to gain momentum and some in both directions across the DNA molecule, connecting with hydrogen-free DNA nucleotides with those produced by each parent Strand add new strands. Since the new composition of nucleotides in each of the parents Strand opposite the connection cost hydrogen, enzymes called DNA polymerase to join nucleotides by phosphodiester bonds. Fact, nucleotides are organized in a base pairing triphosphates other deoxynucleoside, composed of nitrogenous bases, deoxyribose, and three phosphates. As the link between the forms of Phosphodiester group 5 'nucleotide phosphate of new and OH 3' nucleotide of the last in a chain of DNA, two phosphates are removed providing energy for communication. Finally, any parent Strand serve as a template for synthesis of additional copies, which leads to the formation of two identical DNA molecules.
