transAlign: using amino acids to facilitate the multiple alignment of protein-coding DNA sequences [PDF]

open access: yesBMC Bioinformatics, 2005
Background Alignments of homologous DNA sequences are crucial for comparative genomics and phylogenetic analysis. However, multiple alignment represents a computationally difficult problem.

Database searching with DNA and protein sequences: An introduction [PDF]

open access: yesBriefings in Bioinformatics, 2000
This review of sequence database searching aims to set out current practice in the area, in order to give practical guidelines to the experimental biologist. It describes the basic principles behind the programs and enumerates the range of databases available in the public domain.

Geno2proteo, a Tool for Batch Retrieval of DNA and Protein Sequences from Any Genomic or Protein Regions

open access: yesJournal of Integrative Bioinformatics, 2019
The interconversion of sequences that constitute the genome and the proteome is becoming increasingly important due to the generation of large amounts of DNA sequence data. Following mapping of DNA segments to the genome, one fundamentally important task

Comparison of DNA Sequences with Protein Sequences

open access: yesGenomics, 1997
The FASTA package of sequence comparison programs has been expanded to include FASTX and FASTY, which compare a DNA sequence to a protein sequence database, translating the DNA sequence in three frames and aligning the translated DNA sequence to each sequence in the protein database, allowing gaps and frameshifts.

Recognition of protein coding regions in DNA sequences

open access: yesNucleic Acids Research, 1982
We give a test for protein coding regions which is based on simple and universal differences between protein-coding and noncoding DNA. The test is simple enough to use without a computer and is completely objective. The test has been thoroughly proven on 400,000 bases of sequence data: it misclassifies 5% of the regions tested and gives an answer of ...

DNA Sequences Are as Useful as Protein Sequences for Inferring Deep Phylogenies

open access: yesSystematic Biology, 2023
Abstract Inference of deep phylogenies has almost exclusively used protein rather than DNA sequences based on the perception that protein sequences are less prone to homoplasy and saturation or to issues of compositional heterogeneity than DNA sequences.

Extended many-item similarity indices for sets of nucleotide and protein sequences

open access: yesComputational and Structural Biotechnology Journal, 2021
Quantification of similarities between protein sequences or DNA/RNA strands is a (sub-)task that is ubiquitously present in bioinformatics workflows, and is usually accomplished by pairwise comparisons of sequences, utilizing simple (e.g.

Two Dimensional Yau-Hausdorff Distance with Applications on Comparison of DNA and Protein Sequences. [PDF]

open access: yesPLoS ONE, 2015
Comparing DNA or protein sequences plays an important role in the functional analysis of genomes. Despite many methods available for sequences comparison, few methods retain the information content of sequences.

Methods for comparing a DNA sequence with a protein sequence [PDF]

open access: yesBioinformatics, 1996
We describe two methods for constructing an optimal global alignment of, and an optimal local alignment between, a DNA sequence and a protein sequence. The alignment model of the methods addresses the problems of frameshifts and introns in the DNA sequence. The methods require computer memory proportional to the sequence lengths, so they can rigorously
