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.
Editor(s): Laura Vargas-Parada |. Subscribe. Through a cell biology lens, the study of gene expression is tightly linked to our understanding of proteins. Since the early work of Christian Anfinsen in the 1950s, we know that the sequence of amino acids in a protein determines its final three-dimensional structure.Following from that, scientists have repeatedly observed that protein structure dictates where it will act and what it will do.ince the early work of Christian Anfinsen in the 1950s, we know that the sequence of amino acids in a protein determines its final three-dimensional structure.
