Abstract

We describe the construction of nano-molecular assemblies using RNA building blocks the human immunodeficiency virus type 1 (HIV-1) dimerization initiation site (DIS) RNA, that forms stable base pairing through a magnesium-dependent loop-loop interaction ("kissing"). RNA building blocks containing two DIS or DIS-like hairpins connected by a two nucleotide linker self-assembled to form specific structures as observed by non-denaturing polyacrylamide gel electrophoresis (PAGE). Furthermore, observation of "real time" formation of the molecular assemblies by circular dichroism (CD) spectroscopy was attempted.
