WebSee Page 1. F) As discussed in class, lin-14and lin-4 are two C. elegans genes that regulate the timing of developmental stages. Inlin-14- mutants, the embryos skip the L1 stage. In lin-14 (gain-of-function) mutants, the embryos repeat the L1 stage. The lin-14 proteins are present in L1 embryonic stage, but absent in subsequent larval stages ...
