Translation needs a a "dictionary": the genetic code.

  1. Ribosomes guide the translation process by binding to mRNA and loading tRNAs.

  2. An attachment site on the tRNA binds to three-base codons on the mRNA, adding amino acids to a growing protein chain, using the genetic code as a "dictionary".

  3. The protein is released from the complex when the ribosomes reads one of three stop codons on the mRNA.
