Translation of the Genetic Code - Protein Synthesis

mRNA is transcribed in the nucleus. This is a molecule of messenger RNA. mRNA is transcribed in the nucleus. codon A U G G G C U U A A A G C A G U G C A C G U U mRNA molecule

A ribosome attaches to the mRNA molecule. A U G G G C U U A A A G C A G U G C A C G U U

Amino acid U A C tRNA molecule A transfer RNA molecule arrives. It brings a specific amino acid to the first three bases (codon) on the mRNA. anticodon The three unpaired bases (anticodon) on the tRNA link up with the codon. A U G G G C U U A A A G C A G U G C A C G U U

U A C C C G Another tRNA molecule comes into place, bringing a second amino acid. Its anticodon links up with the second codon on the mRNA. A U G G G C U U A A A G C A G U G C A C G U U

U A C C C G Peptide bond A peptide bond forms between the two amino acids. A U G G G C U U A A A G C A G U G C A C G U U

U A C C C G The first tRNA molecule releases its amino acid and moves off into the cytoplasm. A U G G G C U U A A A G C A G U G C A C G U U

C C G The ribosome moves along the mRNA to the next codon. A U G G G C U U A A A G C A G U G C A C G U U

C C G A A U Another tRNA molecule brings the next amino acid into place. A U G G G C U U A A A G C A G U G C A C G U U

C C G C C G A peptide bond joins the second and third amino acids to form a polypeptide chain. A U G G G C U U A A A G C A G U G C A C G U U

A C G G U C The process continues. The polypeptide chain gets longer. This continues until a termination (stop) codon is reached. The polypeptide is then complete. A U G G G C U U A A A G C A G U G C A C G U U
