around their body and undergo ecdysis and molting. Procedure: Cytochrome-c oxidase is the amino acid sequence of a protein that is an essential component of the electron transport chain in aerobic respiration. Therefore it is present in all aerobic organisms and is a good tool to help with molecular phylogenetic studies. Each student in class was given certain organisms and they had to compare the organisms’ cytochrome-c oxidase sequences to look for differences in the sequences of amino acids. The students
