There are small colored rectangles (red, blue, and other colors) positioned along the circle's edge near the top right, with labels including "MCS", "LacR binding site", and "Plac". On the right side of the circle is a vertical list of text labels including "ApaI", "EcoRI", "BamI", "SacI", "KpnI", "AvaI", "SmaI", "XmaI", "BamHI", "XbaI", "SalI", "HincII", "AccI", "SspI", "PstI", "SphI", and "HindIII".
