Référence de la vidéo 11935447
DNA synthesis, animation. DNA (deoxyribonucleic acid) is made up of a two chains of many small molecules, known as nucleotides. Two of these strands are twisted around each other to form a double helix. In order to divide cells need to copy this double-stranded DNA. Firstly the DNA helix is unwound so that the two separated strands of DNA can now act as templates for the production of two new complimentary DNA strands. In this animation a DNA polymerase adds, step by step, a new deoxynucleotide triphosphate at the 3 prime end of the growing DNA strand (bottom). A phosphodiester bond is formed between this nucleotide and the one belonging to the template strand (top). Hydrogen bonds then link the complementary bases together (white).
