Efficient haplotype matching between a query and a panel for genealogical search.

Motivation: With the wide availability of whole-genome genotype data, there is an increasing need for conducting genetic genealogical searches efficiently. Computationally, this task amounts to identifying shared DNA segments between a query individual and a very large panel containing millions of haplotypes. The celebrated Positional Burrows-Wheeler Transform (PBWT) data structure is a pre-computed index of the panel that enables constant time matching at each position between one haplotype and an arbitrarily large panel.

The long noncoding RNA acts as an intranuclear organizing hub for pre-mRNA molecules.

Molecular mechanisms by which long noncoding RNA (lncRNA) molecules may influence cancerous condition are poorly understood. The aberrant expression of lncRNA, encoded within the drosophila gene homolog intron, is correlated with a variety of cancers, including human melanomas. We demonstrate by SHAPE-seq and dChIRP that RNA secondary structure has a core pseudoknotted domain.

WebSTAR3D: a web server for RNA 3D structural alignment.

Unlabelled: The WebSTAR3D web server is a user-friendly online interface for the alignment of RNA 3D structures. The website takes as input two files, each of which can be in either PDB or mmCIF format, containing the desired structures to align, via a PDB code or user upload. In return, the user is presented with a visualization of the aligned structures in Jmol or JSmol, along with the corresponding sequence alignment, and the option to download the nucleotide mapping of the structures and a PDB file containing the aligned, superimposed structures.
