  2. Sequence alignment - Wikipedia

    en.wikipedia.org/wiki/Sequence_alignment

    In bioinformatics, a sequence alignment is a way of arranging the sequences of DNA, RNA, or protein to identify regions of similarity that may be a consequence of functional, structural, or evolutionary relationships between the sequences. [1] Aligned sequences of nucleotide or amino acid residues are typically represented as rows within a matrix.

  3. Sequence assembly - Wikipedia

    en.wikipedia.org/wiki/Sequence_assembly

    In bioinformatics, sequence assembly refers to aligning and merging fragments from a longer DNA sequence in order to reconstruct the original sequence. [1] This is needed as DNA sequencing technology might not be able to 'read' whole genomes in one go, but rather reads small pieces of between 20 and 30,000 bases, depending on the technology used. [1]

    The National Center for Biotechnology Information (NCBI) [1] [2] is part of the (NLM), a branch of the National Institutes of Health (NIH). It is approved and funded by the government of the United States. The NCBI is located in Bethesda, Maryland, and was founded in 1988 through legislation sponsored by US Congressman Claude Pepper.

  5. International Nucleotide Sequence Database Collaboration

    en.wikipedia.org/wiki/International_Nucleotide...

    The International Nucleotide Sequence Database Collaboration (INSDC) consists of a joint effort to collect and disseminate databases containing DNA and RNA sequences. [1] It involves the following computerized databases: NIG's DNA Data Bank of Japan (), NCBI's GenBank and the EMBL-EBI's European Nucleotide Archive ().

  6. Multiple sequence alignment - Wikipedia

    en.wikipedia.org/wiki/Multiple_sequence_alignment

    Multiple sequence alignment (MSA) is the process or the result of sequence alignment of three or more biological sequences, generally protein, DNA, or RNA. These alignments are used to infer evolutionary relationships via phylogenetic analysis and can highlight homologous features between sequences.

  7. Gap penalty - Wikipedia

    en.wikipedia.org/wiki/Gap_penalty

    A global alignment performs an end-to-end alignment of the query sequence with the reference sequence. Ideally, this alignment technique is most suitable for closely related sequences of similar lengths. The Needleman-Wunsch algorithm is a dynamic programming technique used to conduct global alignment. Essentially, the algorithm divides the ...

    Written Definitions: Each glossary entry has a written definition that has been reviewed for clarity and accuracy by teams of science educators and genetic researchers. All of the definitions were written by the same Ph.D.-level science writer for consistency and accuracy. Illustrations:

  9. BLAT (bioinformatics) - Wikipedia

    en.wikipedia.org/wiki/BLAT_(bioinformatics)

    Alignment of multiple mRNA sequences onto a genome assembly in order to infer their genomic coordinates; [10] Alignment of a protein or mRNA sequence from one species onto a sequence database from another species to determine homology. Provided the two species are not too divergent, cross-species alignment is generally effective with BLAT.
