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: Tertiary and Quaternary Structures. The tertiary structure of a protein is a description of the complex and irregular folding of the peptide chain in three dimensions. It is essentially a picture of what the shape of the entire protein actually looks like.
