Goal 4: Translation

Goal 4:Translation

1

I. Protein Synthesis Translation- the process of making proteins from mRNAB. 5 STEPS mRNA travels from the nucleus to a ribosome in the cytoplasm.tRNA, which carries amino acids, also travels to the ribosome from the cytoplasm.Start codon (AUG)- this is the first codon on the mRNA that pairs up with the anticodon on the tRNA What are the bases it pairs up with?UAC2

1 & 233Protein synthesis (cont)STEPS (cont.) amino acids attach to each other as codons and anticodons paira. Amino acids link by peptide bonds b. polypeptide chain forms (many amino acids linked together)5. Stop codon (UAA, UAG, or UGA) - these codons are the signals that tell the ribosome to stop translating a. mRNA is released and the polypeptide (protein) is complete 4
