Different structures of MBs: (a) general DNA MBs with stem-loop structures; (b) modified MB: dsDNA with fluorophore donor and acceptor; (c) chimeric RNA-DNA molecular beacon with RNA loop and DNA stem98; (d) sequences of LNA MB with most LNAs remaining in the stem part and alternate LNAs in the loop part (red italic letters represent LNA bases, and underlined letters are bases for the MB stem)99; (e) stemless PNA MB100.
