DNA missense point mutation, animation

Référence de la vidéo 12082091
DNA missense point mutation. Animation showing a strand of DNA (deoxyribonucleic acid) unravelling to display its genetic code, followed by an illustration of a missense point mutation. A helicase enzyme (red) is shown moving along the DNA molecule, separating the complementary strands. The genetic code is the sequence of the nucleotide bases along a strand (cytosine, C, blue; guanine, G, yellow; adenine, A, green; thymine, T, red). The sequence is labelled here, with adjacent groups of three bases known as codons, which code for the production of amino acids (the basis of proteins). The central codon here is ACC (for the amino acid threonine). This is shown mutating to ATC, which will produce a different amino acid (isoleucine). This is known as a missense mutation, as opposed to mutations that produce nonsense or no change (a silent mutation).
