I. TRANSLATION

A. Amino acids are coded by mRNA base sequences 1. Translation converts mRNA messages into proteins. 2. A codon is a sequence of three nucleotides that codes for an amino acid. codon for methionine (Met) leucine (Leu)

3. The genetic code matches each codon to its amino acid. The genetic code matches each RNA codon with its amino acid or function.

B. Amino acids are linked to become a protein 1. An anticodon is a set of three nucleotides that is complementary to an mRNA codon. 2. An anticodon is carried by a tRNA.

3. Steps: mRNA enters a ribosome. A complementary tRNA molecule binds to the exposed codon, bringing its amino acid.

The ribosome forms a bond between amino acids. Once the stop codon is reached, the ribosome releases the amino acid chain.

After the amino acid chain is released, it can be folded into the final protein.
