In molecular biology and bioinformatics, the consensus sequence is the calculated order of most frequent residues, either nucleotide or amino acid, found at each position in a sequence alignment.

What is meant by consensus sequence?

A consensus sequence is a sequence of DNA, RNA, or protein that represents aligned, related sequences. ... In proteins, consensus sequences may represent entire protein molecules or short fragments of them that correspond to conserved regions of importance for structure and function.

What is a consensus sequence in DNA?

A theoretical representative nucleotide or amino acid sequence in which each nucleotide or amino acid is the one which occurs most frequently at that site in the different sequences which occur in nature. The phrase also refers to an actual sequence which approximates the theoretical consensus.
