14.2 Protein Synthesis

Genetic Code

• Codon-3 base mRNA code

• Start Codon-Starts the Amino Acid

• Stop Codon-Stops the Amino Acid

Codon Wheel

• mRNA CAC = His

• mRNA GCA = Ala

• mRNA UGC = Cys

• mRNA AUG = Start (Met)

• mRNA UGA = STOP

• mRNA UAA = STOP

• mRNA UAG = STOP

Translation

• Ribosomes use the mRNA codons to assemble protein (amino acids)

• mRNA code to Amino Acid chain

• Begins with start codon AUG (Met)

• Codons determine amino acid

• Amino acid chains make proteins

• Stop codon ends the chain
