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.
Proteins are made up of amino acids, the building blocks, linked together. A typical protein may contain 300 or more amino acids. Each protein has its own specific number and sequence of amino acids. The shape of the molecule is important as it often determines the function of the protein.
