[Cytophotometric studies on the levels of proteins and RNA in the nuclei of the apical crest ane the epiblast of the limb bud of the green lizard (Lacerta viridis Laur.) and the blindworm (Anguis fragilis L)].
Cytophotometric determinations establish that in the limb buds of young embryos of the slow worm (Anguis fragilis L.) and of the green lizard (Lacerta viridis Laur.) the level of nuclear proteins and RNA is higher in the cells of the apical crest than in the cells of the epiblast on either side of the crest. This relative increase is progressively y reduced.
