Abstract:
Fluorescence sensing of single bulge-containing double-stranded RNAs was achieved using a triplex forming peptide nucleic acid (PNA) carrying a thiazole orange (TO) base surrogate, where the TO base surrogate facing the bulged nucleotide exhibited a light-up response through triplex formation between the PNA sequence and target purine tracts in dsRNA.

Nucleic acids
DNA and RNA
The two main types of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA is the genetic material in all living organisms, ranging from single-celled bacteria to multicellular mammals. It is in the nucleus of eukaryotes and in the organelles, chloroplasts, and mitochondria. In prokaryotes,...
RNA Structure
The basic structure of RNA consists of a five-carbon sugar and one of four nitrogenous bases. Although most RNA is single-stranded, it can form complex secondary and tertiary structures. Such structures play essential roles in the regulation of transcription and translation.
Different Types of RNA Have the Same Basic Structure
There are three main types of ribonucleic acid (RNA): messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). All three RNA types consist of a...
