Fig. 1From: Expression of ribosomopathy genes during Xenopus tropicalis embryogenesis a Schematic of ribosome biogenesis. The rDNA is transcribed by RNA polymerase I and the resulting rRNA is processed in the nucleolus before being incorporated into the large ribosomal subunit (LSU) or small ribosomal subunit (SSU). b Schematic of X. tropicalis embryos at examined stages. Major anatomical features are labeled. A: anterior, P: posterior, D: dorsal, R: ventralBack to article page
