mRNA splicing, animation

Référence de la vidéo 11936712
mRNA splicing, animation. mRNA (messenger ribonucleic acid) is the intermediary between DNA (DNA) and its protein product. Before the mRNA can be translated into amino acids, the building blocks of proteins, introns (non-coding regions, red) need to be removed. This process is known as splicing and leaves only exons (coding regions, blue). The splicing is carried out by proteins and enzymes collectively termed a spliceosome. Two snRNPs (small nuclear ribonucleoproteins, top) bind to the ends of introns and draw them together before cutting them away from the mRNA strand. The excised introns are then lysed (degraded), and the strands of exons are joined and translated into chains of amino acids. For a labelled version of this animation, see K004/2024.
