The nucleotides or amino acids most commonly found at each position in the sequences of related DNAs, RNAs, or proteins. See also homology.
Average or most typical form of a sequence that is reproduced with minor variations in a group of related DNA, RNA, or protein sequences. The consensus sequence shows the nucleotide or amino acid most often found at each position. The preservation of a consensus implies that the sequence is functionally important.
A sequence pattern derived from the alignment of multiple sequences that represents the nucleotide or amino acid most likely to occur at each position in a sequence. Consensus sequences are used to identify DNA sequence features and protein families, and
a hypothetical sequence made up of the nucleotides found most often in each position
an idealized sequence in which each position represents the base most often found when many actual sequences are compared
an idealized sequence of bases whose real counterparts appear in various places in a polynucleotide and perform the same function in each, but with minor deviations of the real sequence from the ideal
a sequence of consensus bases
a sequence of the most common nucleotide or amino acid at each position in an alignment
A term that refers to sequences common to different genes within an organism, or to the same gene among different organisms, that encode a specific function. This term may be applied to either nucleic acids or proteins, since the protein sequence is completely dependent upon the nucleic acid sequence.
A pseudo-sequence that summarises the residue information contained in a multiple alignment.
nucleotide or amino acid sequences that show significant similarity but are not identical. A sequence constructed by choosing at each position the residue that is found there most often in the group of sequen ces under consideration.
A idealized nucleotide sequence that represents a sequence that serves some particular function (e.g. a promoter) at multiple places in a genome. Each position of the consensus sequence represents the nucleotide most often found at that position in the real sequences. The precise sequence will vary from site to site, but they all are similar to the consensus sequence.
represents an idealized sequence in which the position of each DNA base pair represents the order most often found when many actual sequences are compared.
A derived base sequence that represents a family of similar sequences.
The most commonly occurring amino acid or nucleotide at each position of an aligned series of proteins or polynucleotides.
A GGGCGGG sequence promoter element to the 5' side of genes in eukaryotes involved in the control of gene expression.
The sequence at a promoter which can vary between slightly but always conforms to an overall pattern known as a consensus sequence.
In molecular biology and bioinformatics, a consensus sequence is a way of representing the results of a multiple sequence alignment, where related sequences are compared to each other, and similar functional sequence motifs are found. The consensus sequence shows which residues are conserved (are always the same), and which residues are variable.
