  1. The genetic code & codon table (article) | Khan Academy

    Codons in an mRNA are read during translation, beginning with a start codon and continuing until a stop codon is reached. mRNA codons are read from 5' to 3' , and they specify the order of …

  2. Stages of translation (article) | Khan Academy

    In an mRNA, the instructions for building a polypeptide come in groups of three nucleotides called codons. Here are some key features of codons to keep in mind as we move forward:

  3. Khan Academy

    Oops. Something went wrong. Please try again. Uh oh, it looks like we ran into an error. You need to refresh. If this problem persists, tell us.

  4. tRNAs and ribosomes (article) | Translation | Khan Academy

    The anticodon of a given tRNA can bind to one or a few specific mRNA codons. The tRNA molecule also carries an amino acid: specifically, the one encoded by the codons that the …

  5. O código genético (artigo) | Khan Academy

    Como a informação contida em uma cadeia de mRNA é decodificada para formar um polipeptídeo? Aprenda como grupos de três nucleotídeos, chamados códons, especificam os …

  6. mRNA code and translation (article) | Khan Academy

    This article goes over how the mRNA code is translated and important concepts related to this process.

  7. DNA function & structure (with diagram) (article) | Khan Academy

    If nucleotides are like letters, then codons are like words. Unlike English, where we use 26 letters to make words of all different lengths and meanings, your cells use the four DNA nucleotide …

  8. Translation (mRNA to protein) (video) | Khan Academy

    Translation occurs in ribosomes, which are cellular structures made of proteins and ribosomal RNA (rRNA). Here, mRNA is converted into amino acid sequences, forming polypeptides. …

  9. Transcription and translation (practice) | Khan Academy

    Learn about RNA and protein synthesis in molecular genetics with this high school biology resource from Khan Academy.

  10. Types of mutations and their notations (article) | Khan Academy

    Frameshift Mutation: If the number of inserted or deleted nucleotides is not a multiple of three, it causes a shift in the reading frame, altering all downstream codons. This can result in a …
