Presentation Transcript

  1. TRANSLATION

  2. TRANSLATION • The process where the mRNA code is translated into amino acids which are combined to make a protein • Occurs on a ribosome

  3. TRANSLATION

  4. mRNA Codon • Group of 3 nucleotides • Each codon codes for a specific amino acid • GCU = Alanine • 64 different codons

  5. Amino Acids (a.a.) • Building blocks of proteins • 20 amino acids and 64 codons, therefore there is more than one codon for each a.a. • Alanine  GCU, GCC, GCA and GCG

  6. Genetic code for a. a. is universal* same for all organisms

  7. Ribosome • Organelles made of ribosomal RNA (rRNA) • Where translation occurs

  8. Transfer RNA (tRNA) • Carries a. a. on one end and carries the anticodon on the other en • Anticodon is the complementary sequence to mRNA codons

  9. STEPS OF TRANSLATION • Anticodon of the first tRNA connects with complementary codon sequence on the mRNA • The next tRNA connects with next complementary codon sequence on the mRNA and the second a. a. is added to a first a.a.

  10. STEPS OF TRANSLATION (continued) 3. One tRNA after another matches up as mRNA moves through the ribosome to form the protein chain

  11. Stop codon • Has no anticodon • Causes ribosome to fall apart and protein is released
