  2. Conserved signature indels - Wikipedia

    en.wikipedia.org/wiki/Conserved_signature_indels

    Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. [1] [2] CSIs, brought about by rare genetic changes, provide useful phylogenetic markers that are generally of defined size and they are flanked on both sides by conserved regions to ensure their reliability.

  3. Conserved sequence - Wikipedia

    en.wikipedia.org/wiki/Conserved_sequence

    Conserved sequences with a known function, such as protein domains, can also be used to predict the function of a sequence. Databases of conserved protein domains such as Pfam and the Conserved Domain Database can be used to annotate functional domains in predicted protein coding genes.

  4. Sequence alignment - Wikipedia

    en.wikipedia.org/wiki/Sequence_alignment

    Motif finding, also known as profile analysis, constructs global multiple sequence alignments that attempt to align short conserved sequence motifs among the sequences in the query set. This is usually done by first constructing a general global multiple sequence alignment, after which the highly conserved regions are isolated and used to ...

  5. Sequence homology - Wikipedia

    en.wikipedia.org/wiki/Sequence_homology

    Bottom: in a separate species , a gene has a similar function (histone-like nucleoid-structuring protein) but has a separate evolutionary origin and so is an analog. Sequence homology is the biological homology between DNA , RNA , or protein sequences , defined in terms of shared ancestry in the evolutionary history of life .

  6. BLOSUM - Wikipedia

    en.wikipedia.org/wiki/BLOSUM

    The BLOSUM62 matrix, the amino acids have been grouped and coloured based on Margaret Dayhoff's classification scheme. Positive and zero values have been highlighted. In bioinformatics, the BLOSUM (BLOcks SUbstitution Matrix) matrix is a substitution matrix used for sequence alignment of proteins.

  7. Genetic marker - Wikipedia

    en.wikipedia.org/wiki/Genetic_marker

    A genetic marker is a gene or DNA sequence with a known location on a chromosome that can be used to identify individuals or species. It can be described as a variation (which may arise due to mutation or alteration in the genomic loci) that can be observed.

  9. Sequence motif - Wikipedia

    en.wikipedia.org/wiki/Sequence_motif

    In biology, a sequence motif is a nucleotide or amino-acid sequence pattern that is widespread and usually assumed to be related to biological function of the macromolecule. For example, an N -glycosylation site motif can be defined as Asn, followed by anything but Pro, followed by either Ser or Thr, followed by anything but Pro residue .
