Translation: Amino acids and exceptions to the genetic code (concept map)

Map summary:

Codons on mRNA pair with anti-codons on TRNA

Genetic code is redundant ( 64 different codons for 20 amino acids)

Redundancy protects from mutation (in principle)

Exceptions to the genetic code: Mitochondria and protists have different start and stop codon identities,

Lastly there are the two nonstandard amino acids which are used via transnational recoding and are not a part of the genetic code itself.
