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 complex molecule composed of amino acids and necessary for the chemical processes that occur in living organisms.Proteins are basic constituents in all living organisms.ome proteins, such as hemoglobin, are composed of more than one protein subunit (polypeptide chain). The spatial conformation of these chains is known as the quaternary structure. Quaternary structure is maintained by the same kinds of forces that determine tertiary structure.
