WebApr 9, 2024 · The earliest distinction between protostomes and deuterostomes is the type of cleavage undergone by the zygote. Protostomes undergo spiral cleavage, meaning that the cells of one pole of the embryo are rotated, and thus misaligned, with respect to the cells of the opposite pole. This is due to the oblique angle of the cleavage. WebContext examples . This leads to the cleavage of poly (ADP-ribose) polymerase and the release of nuclear matrix proteins (NuMA).
