"in double inactivation experiments, cooperation was observed between
lin-15B and
llin-35 Rb, rather than
lin-15B and
cki-1,2 Cip/Kip (Figure 2D; data not shown). Loss of either
lin-15B or
lin-35 alone did not cause additional cell division, while
lin-35;
lin-15B double RNAi resulted in supernumerary cell divisions, n = 10 animals)... we used the strong or complete loss-of-function alleles
lin-35(
n745) and
lin-15B(
n374) and obtained similar results (Figure 2D)."
