Multiple sequence alignment: in pursuit of homologous DNA positions.
DNA sequence alignment is a prerequisite to virtually all comparative genomic analyses, including the identification of conserved sequence motifs, estimation of evolutionary divergence between sequences, and inference of historical relationships among genes and species. While it is mere common sense that inaccuracies in multiple sequence alignments can have detrimental effects on downstream ana...
متن کاملDNA Sequence Alignment by Microhomology Sampling during Homologous Recombination
Homologous recombination (HR) mediates the exchange of genetic information between sister or homologous chromatids. During HR, members of the RecA/Rad51 family of recombinases must somehow search through vast quantities of DNA sequence to align and pair single-strand DNA (ssDNA) with a homologous double-strand DNA (dsDNA) template. Here, we use single-molecule imaging to visualize Rad51 as it a...
متن کاملMultiple Sequence Alignment Multiple Sequence Alignment
An algorithm for progressive multiple alignment of sequences with insertions " , 1. Introduction The problem of sequence alignment is to find the patterns of sequence conservation and similarity between pairs or sets of given sequences. In biological contexts, similarity between biological sequences usually amounts to either functional or structural similarities or divergence from a common ance...
متن کاملMultiple sequence alignment.
Multiple sequence alignments are an essential tool for protein structure and function prediction, phylogeny inference and other common tasks in sequence analysis. Recently developed systems have advanced the state of the art with respect to accuracy, ability to scale to thousands of proteins and flexibility in comparing proteins that do not share the same domain architecture. New multiple align...
متن کاملMultiple protein sequence alignment.
Multiple sequence alignments are essential in computational analysis of protein sequences and structures, with applications in structure modeling, functional site prediction, phylogenetic analysis and sequence database searching. Constructing accurate multiple alignments for divergent protein sequences remains a difficult computational task, and alignment speed becomes an issue for large sequen...
