  4. Transcription and mRNA processing - Khan Academy

    Transcription is when we take the information encoded in the gene in DNA and encode essentially that same information in mRNA. So transcription we are going from DNA to messenger RNA, and we're …

  5. Eukaryotic pre-mRNA processing | RNA splicing (article) - Khan Academy

    The molecule that's directly made by transcription in one of your (eukaryotic) cells is called a pre-mRNA, reflecting that it needs to go through a few more steps to become an actual messenger RNA (mRNA).

  6. Les étapes de la transcription (leçon) | Khan Academy

    La transcription est une étape essentielle de l'exploitation des informations génétiques de notre ADN pour fabriquer des protéines. Les protéines sont les molécules clés qui structurent les cellules et les …

  7. Transcription and mRNA processing (article) | Khan Academy

    During transcription, a gene's nucleotide sequence (DNA) is copied to form messenger RNA (mRNA), which serves as a temporary blueprint. In eukaryotes, this occurs in the nucleus.
