What must occur for protein translation to begin? A water molecule must be added to the protein chain. A peptide bond must form between subunits of mRNA. The amino acid Cys must be picked up by tRNA. The codon AUG must be identified.

Respuesta :

For protein translation to begin, the codon AUG must be identified.

PROTEIN SYNTHESIS:

  • Protein synthesis is the process whereby living organisms synthesize proteins using the information stored in their DNA. Protein synthesis involves transcription and translation.

  1. Transcription occurs in the nucleus where DNA is used as a template to synthesize mRNA.
  2. Translation occurs in the ribosome where mRNA transcript is used to synthesize amino acid sequence.

  • During translation, mRNA codons are read and binded to by the anticodons of a tRNA molecule.

However, for translation to begin, a specific mRNA codon called START CODON with the sequence: AUG must be identified first.
