Structure defines function (protein) change order of amino acid changes protein. Hemoglobin, sequence of amino acids Thr,Pro, GLU,(charged) Glu Sickle cell anemia-Thr, Pro, VAL,(non-polar) Glu **hydrophobic. -aggregate together. Fibers of abnormal hemoglobin deform cell into sickle cell. Locks up blood vessels. Three letter amino acid Denaturation- take protein and change structure. Heat it up or do something to change structure. Folded protein unfolds to linear peptide chain. Chaperonins- protein folding. Nucleic acids. 1 synthesis of mRNA in the nucleus. 2. movement of mRNA into cytoplasm. 3. synthesis of protein. TRANSCRIPTION. The chemical composition on DNA. Polymoer, made up of repeating nucleotides.
