Fig. 2

Schematic illustration of the functional units of the octopus haemocyanin gene and the partial regions analysed in this study. Conserved binding sites of the degenerate forward and reverse primers are marked with the corresponding amino acid sequence WAIWQ or PYWDW. Resulting amplicons spanned a region between the functional units f and g and a region within the functional unit g. Fragment lengths are indicated before (in line) and after sequence trimming (in parentheses).
