(A) Microscopic images of 3-dpf zebrafish embryos injected with gene-specific MO with or without p53 MO. Original magnification, ×50. (B) The percentage of normal, affected, and dead fish was scored for all gene MO injections (+p53 MO and –p53 MO) at 3 dpf and plotted. dpf, days post fertilization; MO, morpholino(s).
