Following statements were made regarding vulval development in C. elegans:
A. The formation of the anchor cell is mediated by lin-12, the C. elegans homologue of the Notch gene.
B. The formation of the anchor cell is mediated by lin-12, the C. elegans homologue of the Delta gene.
C. The lin-12 gene needs to function only in that cell destined to become the uterine precursor cell.
D. Presumptive Anchor cell also need lin-12.
E. Two cells originally synthesize both the signal for uterine differentiation (the LAG-2 protein, homologous to Delta) and the receptor for this molecule (the LIN-12 protein, homologous to Notch.
