Compensatory evolution of a precursor messenger RNA secondary structure in the Drosophila melanogaster Adh gene.
Evidence for the evolutionary maintenance of a hairpin structure possibly involved in intron processing had been found in intron 1 of the alcohol dehydrogenase gene (Adh) in diverse Drosophila species. In this study, the putative hairpin structure was evaluated systematically in Drosophila melanogaster by elimination of either side of the stem using site-directed mutagenesis. The effects of the...
متن کاملRibosomal RNA secondary structure: compensatory mutations and implications for phylogenetic analysis.
Using sequence data from the 28S ribosomal RNA (rRNA) genes of selected vertebrates, we investigated the effects that constraints imposed by secondary structure have on the phylogenetic analysis of rRNA sequence data. Our analysis indicates that characters from both base-pairing regions (stems) and non-base-pairing regions (loops) contain phylogenetic information, as judged by the level of supp...
متن کاملReconstructing phylogeny from RNA secondary structure via simulated evolution
DNA sequences of genes encoding functional RNA molecules (e.g., ribosomal RNAs) are commonly used in phylogenetics (i.e. to infer evolutionary history). Trees derived from ribosomal RNA (rRNA) sequences, however, are inconsistent with other molecular data in investigations of deep branches in the tree of life. Since much of te functional constraints on the gene products (i.e. RNA molecules) rel...
متن کاملRNA secondary structure design.
We consider the inverse-folding problem for RNA secondary structures: for a given (pseudo-knot-free) secondary structure we want to find a sequence that has a certain structure as its ground state. If such a sequence exists, the structure is called designable. We have implemented a branch-and-bound algorithm that is able to do an exhaustive search within the sequence space, i.e., gives an exact...
متن کاملRNA Secondary Structure Prediction.
In this unit, protocols are provided for predicting RNA secondary structure with the user-friendly RNAstructure desktop computer program and the RNAstructure Web server. The minimum free energy structure and a set of suboptimal structures with similar free energies are predicted. Prediction of high-affinity oligonucleotide binding sites to a structured RNA target is also presented. © 2016 by Jo...
