A large ribosomal subunit bonds to the initiation complex. The codon adjacent to the initiation codon bonds to its complementary anticodon, which is part of a free tRNA. The two amino acids still attached to their tRNAs align. With the help of rRNA, amino acids form peptide bonds. Then, the first tRNA is released.
Primary Structure (Peptide Bonds) The primary structure of a protein consists of amino acids chained to each other. Amino acids are joined by peptide bonds. A peptide bond is a type of covalent bond between the carboxyl group of one amino acid and the amino group of another amino acid. Amino acids themselves are made of atoms joined together by covalent bonds. Secondary Structure (Hydrogen Bonds) The secondary structure describes the three-dimensional folding or coiling of a chain of amino acids (e.g., beta-pleated sheet, alpha helix).
