## Abstract Blastocysts were collected from the uteri of intact or ovariectomized mice and incubated with or without actinomycin D in a medium containing [^14^C] amino acids. In the absence of actinomycin D the rate of amino acid incorporation by blastocysts from intact mice (i.e., normal embryos)
## Abstract Oocyte ribosomes stimulate H^3^β5βuridine incorporation into RNA when microinjected into the vegetal cells of early cleavage embryos. Preparations with a low percentage of monosomes, such as those of swimming larvae and adult frog liver, give little stimulation. E. __coli__ ribosomes fa
