  3. Overview of translation (article) | Khan Academy

    There are 61 codons for amino acids, and each of them is "read" to specify a certain amino acid out of the 20 commonly found in proteins. One codon, AUG, specifies the amino acid methionine and also …

  4. The genetic code (article) | Khan Academy

    As we saw above, the genetic code is based on triplets of nucleotides called codons, which specify individual amino acids in a polypeptide (or "stop" signals at its end).

  5. Stages of translation (article) | Khan Academy

    An in-depth look how polypeptides (proteins) are made. Initiation, elongation, and termination.

  6. 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 aminoácidos (bem …

  9. 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 tRNA binds.

  10. 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. Transfer RNA …
