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.
By definition, the structure of a protein is based on the linear sequence of amino acids (primary structure) combined with how these amino acids interact with each other. These interactions occur within a single protein (secondary and tertiary structure) and between proteins (quaternary structure).
