(a) Distribution of PQS (G-score ≥ 30) within mouse 47S pre-rRNA (Genebank: BK000964.3). (b) FISH of pre-18S and pre-28S in GO and FGO. Triangles indicate the nucleolus or NLB in the oocytes.

(a) FISH of pre-18S and pre-28S rRNA in mouse early embryos. Yellow triangles indicate pre-rRNA signal within the NPB or nucleolus. Scale bar, 20 μm. (b) Fluorescence of CYTO signal in mouse ...

the small subunit contains the 16S rRNA, while in eukaryotes, it contains the 18S rRNA. These rRNAs are involved in mRNA binding and decoding. Large Subunit rRNAs: The large subunit in prokaryotes ...
