• Translation converts m. RNA messages into polypeptides. • The m. RNA is

• Translation converts m. RNA messages into polypeptides. • The m. RNA is always read in groups of 3 • A codon is a sequence of three nucleotides that codes for an amino acid. codon for methionine (Met) codon for leucine (Leu)

• The genetic code matches each codon to its amino acid or function.

• The genetic code matches each codon to its amino acid or function. • Codon chart applies to all living things (universal language) The genetic code matches each RNA codon with its amino acid or function.

• Once the m. RNA reaches the ribosome the t. RNA will match

• Once the m. RNA reaches the ribosome the t. RNA will match its anticodon to the codon. • An anticodon is a set of three nucleotides that is complementary to an m. RNA codon. • The t. RNA also has the matching amino acid attached Has both an anticodon and matching amino acid 8

• Ribosomes move along the m. RNA and adds an amino acid for

• Ribosomes move along the m. RNA and adds an amino acid for each codon read. The amino acids are bonded with peptide bonds 6

• For translation to begin, t. RNA binds to a start codon and

• For translation to begin, t. RNA binds to a start codon and signals the ribosome to assemble. – A complementary t. RNA molecule binds to the exposed codon, bringing its amino acid close to the first amino acid.

– The ribosome helps form a polypeptide bond between the amino acids. – The

– The ribosome helps form a polypeptide bond between the amino acids. – The ribosome pulls the m. RNA strand the length of one codon. 7 5

– The now empty t. RNA molecule exits the ribosome. – A complementary t.

– The now empty t. RNA molecule exits the ribosome. – A complementary t. RNA molecule binds to the next exposed codon. Once the stop codon is reached, the ribosome releases the protein and disassembles.
