Document Summary
Each neuron has a nucleus, the same # of chromosomes, all contain dna which is made of a sequence that is unique to you. The shape of your dna is in a double helix comprised of 4 nucleotides arranged in pairs that leads to the production of proteins. The overall process: dna -> transcription -> mrna molecule that represent that sae dna code-> translation into -> polypeptide chain, an amino acid comprised of arg, phe, gly, A proteins shape and its ability to change shape and to combine with other proteins are central to its function; protein is combined of amino acids. 4 levels of protein structure: whether a polypeptide chain forms a pleated sheet or a helix and its ultimate three-dimensional shape are both determined by the sequence of amino acids in the primary structure. 4: or be extracted from the cell by exocytosis (exportation out of the cell) remain within the cell to act as enzyme.
