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.
In this lesson, the three-dimensional structure of proteins will be discussed: the primary structure of polypeptides, secondary structures found in proteins (Î±-helix, Î²-sheet), and the tertiary structure. The concept of an enzyme active site will be introduced.
