DNA nonsense point mutation, animation

Videonummer 12269533
DNA nonsense point mutation. Animation showing a strand of DNA (deoxyribonucleic acid) unravelling to display its genetic code, followed by an illustration of a nonsense 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 GGA (for the amino acid glycine). This is shown mutating to TGA, which is a stop codon. This truncates the protein production, causing abnormal shortening. This is known as a nonsense mutation, as opposed to mutations that produce change (a missense mutation) or no change (a silent mutation).
