Abstract:
The specific binding of the lambda N protein to a 15 nucleotide RNA oligomer that forms a hairpin structure has been investigated by biophysical methods. Using fluorescence spectroscopy and equilibrium ultra-centrifugation, it was found that the N protein binds specifically to this RNA hairpin as a monomer. Circular dichroism experiments show that both the N protein and the RNA hairpin undergo structural change upon association of the complex.

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.
