Localization of a segment of 16S RNA on the surface of the small ribosomal subunit by immune electron microscopy of complementary oligodeoxynucleotides.

abstract：:Adenosine to inosine (A-to-I) modification by the ADAR (adenosine deaminase that acts on RNA) enzymes perform the most common type of RNA editing in metazoans. ADARs use double stranded RNA as substrates but allow interruptions of bulges and loops in the structure. It is well known that these enzymes can use messenger...
