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.
Many of the proteins can move about within the phospholipid bilayer, while other proteins are anchored in place by the cytoskeletal structures. This attachment of proteins to the underlying cytoskeleton produces characteristic shapes of the cells. Objective 3: Describe the function of 3 categories of membrane proteins.
