The 18S ribosomal RNA m6 A methyltransferase Mettl5 is required for normal walking behavior in Drosophila. [PDF]
EMBO Rep, 2020 RNA modifications have recently emerged as an important layer of gene regulation. N6‐methyladenosine (m6A) is the most prominent modification on eukaryotic messenger RNA and has also been found on noncoding RNA, including ribosomal and small nuclear RNA.

18S Ribosomal RNA Evaluation as Preanalytical Quality Control for Animal DNA. [PDF]
Biomed Res Int, 2016 The 18S ribosomal RNA (rRNA) gene is present in all eukaryotic cells. In this study, we evaluated the use of this gene to verify the presence of PCR-amplifiable host (animal) DNA as an indicator of sufficient sample quality for quantitative real-time PCR

18S ribosomal RNA and tetrapod phylogeny. [PDF]
Systematic Biology, 2003 Previous phylogenetic analyses of tetrapod 18S ribosomal RNA (rRNA) sequences support the grouping of birds with mammals, whereas other molecular data, and morphological and paleontological data favor the grouping of birds with crocodiles.

Structural and functional analysis of Utp24, an endonuclease for processing 18S ribosomal RNA. [PDF]
PLoS ONE, 2018 The precursor ribosomal RNA is processed by multiple steps of nucleolytic cleavage to generate mature rRNAs. Utp24 is a PIN domain endonuclease in the early 90S precursor of small ribosomal subunit and is proposed to cleave at sites A1 and A2 of pre-rRNA.

Primary structure of rabbit 18S ribosomal RNA determined by direct RNA sequence analysis. [PDF]
Nucleic Acids Research, 1984 The primary structure of rabbit 18S ribosomal RNA was determined by nucleotide sequence analysis of the RNA directly. The rabbit rRNA was specifically cleaved with T1 ribonuclease, as well as with E.

Nucleotide sequence of a crustacean 18S ribosomal RNA gene and secondary structure of eukaryotic small subunit ribosomal RNAs. [PDF]
Nucleic Acids Research, 1984 The primary structure of the gene for 18 S rRNA of the crustacean Artemia salina was determined. The sequence has been aligned with 13 other small ribosomal subunit RNA sequences of eukaryotic, archaebacterial, eubacterial, chloroplastic and plant ...
