The genetic code links groups of nucleotides in an mRNA to amino acids in a protein. Start codons, stop codons, reading frame.

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 …

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).

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

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 …

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.
