The genetic code & codon table (article) | Khan Academy
The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.
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).
O código genético (artigo) | Tradução | Khan Academy
O código genético liga grupos de nucleotídeos de um RNAm a aminoácidos de uma proteína. Códons de início, códons de parada, pauta de leitura.

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 …
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 …
Mutations (apply) (practice) | Khan Academy
The gene’s reading frame is indicated by the spacing between the three-nucleotide codons. These codons can be translated using a table like the one included below, which shows the amino acid …
