Consensus sequence
Consensus Sequence
A Consensus Sequence (pronounced: kuh n-sen-suh s see-kwuh ns) is a sequence of DNA or RNA that is derived from the alignment and comparison of multiple sequences within a genome or proteome. It represents the most common nucleotide or amino acid at each position.
Etymology
The term "Consensus Sequence" is derived from the Latin word "consensus", meaning agreement, and the English word "sequence", referring to a particular order in which related things follow each other.
