Defence and foreign policy. One of the key reasons for Federation was to achieve a united defence force which could better protect Australia. Around the 1880s, the Australian colonies had become increasingly concerned over the close proximity of foreign powers.
Protein Structure Determination. The three-dimensional shape of a protein is determined by its primary structure. The order of amino acids establishes a protein's structure and specific function. The distinct instructions for the order of amino acids are designated by the genes in a cell.
Tertiary Structure: The Overall 3-Dimensional Shape of a Protein. A protein needs to adopt a final and stable 3-dimensional shape in order to function properly. The Tertiary Structure of a protein is the arrangement of the secondary structures into this final 3-dimensional shape. The sequence of amino acids in a protein (the primary structure) will determine where alpha helices and beta sheets (the secondary structures) will occure.
