αr9 is a family of bacterial small non-coding RNAs with representatives in a broad group of α-proteobacteria from the order Hyphomicrobiales. The first member of this family (Smr9C) was found in a Sinorhizobium meliloti 1021 locus located in the chromosome (C).
Antisense RNA
RNA MOLECULES HYBRIDIZING TO COMPLEMENTARY SEQUENCES IN EITHER RNA OR DAN, ALTERING THE FUNCTION OF THE LATTER
Rna, antisense; Antisense rna; Antisense mRNA; Anti-sense RNA; AsRNA; Antisense gene
Antisense RNA (asRNA), also referred to as antisense transcript, natural antisense transcript (NAT) or antisense oligonucleotide, is a single stranded RNA that is complementary to a protein coding messenger RNA (mRNA) with which it hybridizes, and thereby blocks its translation into protein. asRNAs (which occur naturally) have been found in both prokaryotes and eukaryotes, and can be classified into short (200 nucleotides) non-coding RNAs (ncRNAs).
RNA editing
COVALENT ALTERATION OF ONE OR MORE NUCLEOTIDES WITHIN AN RNA MOLECULE TO PRODUCE AN RNA MOLECULE WITH A SEQUENCE THAT DIFFERS FROM THAT CODED GENETICALLY
RNA Editing; Rna editing; Editosome; RNA modification
RNA editing (also RNA modification) is a molecular process through which some cells can make discrete changes to specific nucleotide sequences within an RNA molecule after it has been generated by RNA polymerase. It occurs in all living organisms and is one of the most evolutionarily conserved properties of RNAs.
