  • Overview of translation (article) | Khan Academy
    Step 1: transcription! Here, the DNA sequence of a gene is "rewritten" in the form of RNA In eukaryotes like you and me, the RNA is processed (and often has a few bits snipped out of it) to make the final product, called a messenger RNA or mRNA Step 2: translation!
  • Khan Academy | Khan Academy

  • DNA transcription and mRNA processing (video) | Khan Academy
    Transcription involves rewriting genetic information from DNA to mRNA, with RNA polymerase playing a crucial role In eukaryotic cells, DNA to mRNA transcription occurs within the nucleus, producing pre-mRNA This pre-mRNA undergoes processing, including the addition of a 5' cap, a poly-A tail, and splicing out introns, resulting in mature mRNA, which then leaves the nucleus for protein
  • Transcription and mRNA processing (article) | Khan Academy
    Transcription includes three steps: initiation (1), elongation (2), and termination (3) During initiation, RNA polymerase attaches to a gene’s promoter During elongation, RNA polymerase moves along the DNA molecule, synthesizing an mRNA molecule that is complementary to the template strand of the DNA
