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 make up about 15% of our body mass. They are the most abundant 'solid' substances in our bodies. Each protein has its own precise function under the direction of its own gene. The shapes of proteins are of key importance. These are determined by the sequence of amino acids that make them up. Amino acids are the building blocks (monomers) of proteins. Twenty different amino acids are used to make the body's proteins.
