Structural and combinatorial constraints on base pairing in large nucleotide sequences

Structural and combinatorial constraints on base pairing in large nucleotide sequences

R Nussinov et al. J Theor Biol. .

Abstract

In this paper we discuss the constraints and combinatorial problems of folding long RNA and single stranded DNA molecules into base paired structures. A computer code FOLD-A was designed to perform base pairing foldings of very long sequence chains and search for low energy configurations. The logic of the FOLD-A algorithm is described in some detail. The applications of FOLD-A to the A-protein gene of MS2 and the whole genome of the phi X 174 phage with over 5300 bases are discussed in the accompanying paper.
