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 have very complex structures which is how their functions come about. Proteins are actually sets of amino acids bonded together. A primary structure is a simple chain of amino acids. The secondary structure is the folding of this chain, and in the tertiary structure the chain folds itself into a three dimensional shape.
