Consensus sequence
Of a series of related dna, rna or protein sequences, the sequence that reflects the most common choice of base or amino acid at each position. Areas of particularly good agreement often represent conserved functional domains.
Consensus sequence
A idealized nucleotide sequence that represents a sequence that serves some particular function (e.g. a promoter) at multiple places in a genome.
Consensus sequence: The nucleotides or amino acids most commonly found at each positions of the sequences of related molecules.
Consensus sequence Idealized base sequence that represents common features of a promoter site.
Conservative substitutions Mutations that replace one amino acid with another similar in size and chemical properties.
Consensus sequence
A minimum nucleotide sequence found to be common (although not necessarily identical) in different genes and in genes from different organisms that is associated with a specific function.
Consensus sequence
- A sequence that is found in most examples of a particular genetic element, and which shows a high degree of conservation. An example is the CAAT box.

CONSENSUS SEQUENCE - A linear series of nucleotides, commonly with gaps and some degeneracy, that define common features of homologous sequences or recognition sites for proteins that act on or bind to nucleic acids.
Consensus sequence: A ‘nominal' sequence inferred from multiple, imperfect examples. Multiple lanes of shotgun sequence can be merged to show a consensus sequence. The optimal sequence of nucleotides recognized by some factor.
A consensus sequence (AGGAGG) upstream of the translation initiation site ATG in bacteria. Important for translation initiation. For species-specific translation initiation sequences in bacteria, please visit Primo.

coli, there are 5 DnaA boxes, each of which contains a highly conserved 9-base pair consensus sequence 5' - TTATCCACA - 3'. [4] Binding of DnaA to this region causes it to become negatively supercoiled.
In large shotgun-sequencing projects, DNA fragments are assembled into a consensus sequence.
Cryptic splice site A DNA sequence which is similar to the consensus sequence of a splice site but which is not normally used. It may be activated if a mutation alters or removes a genuine nearby site.
The nucleotide sequence of promoters is similar but not identical. The more similar the sequence is to a consensus sequence, the more likely that RNA polymerase will attach and produce mRNA from the associated genes.
programs that try to predict genes look for what we call "splicing sites," the sites that are used to splice one exon onto another exon in an RNA. We've got a little information about the nature of splicing sites. There [are] some consensus sequences, ...
