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.
Protein function is dependent on its tertiary structure. Proteins tend to fold into three-dimensional structures because of the sequence of amino acids. Proteins also contain functional groups from each amino acid. These groups are reactive and also contribute to protein function. Proteins also interact with one another and with other macromolecules.
