From earliest to latest, the overall sequence of early development proceeds as follows:
A)first cell division → synthesis of embryo's DNa begins → acrosomal reaction → cortical reaction
B)cortical reaction → synthesis of embryo's DNA begins → acrosomal reaction → first cell division
C)cortical reaction → acrosomal reaction → first cell division → synthesis of embryo's DNA begins
D)first cell division → synthesis of embryo's DNA begins → acrosomal reaction → cortical reaction
E)acrosomal reaction → cortical reaction → synthesis of embryo's DNA begins → first cell division

Question

Quizplus · Accepted Answer

The acrosomal reaction occurs first during fertilization, followed by the cortical reaction to prevent polyspermy. Then, the synthesis of the embryo's DNA begins, and finally, the first cell division occurs.
