Clustal Omega is a new multiple sequence alignment program that uses seeded guide trees and HMM profile-profile techniques to generate alignments between three or more sequences. For the alignment of two sequences please instead use our pairwise sequence alignment tools. Input sequence. Sequence Type. Protein. DNA. RNA.
Multiple sequence alignment ( MSA) is the process or the result of sequence alignment of three or more biological sequences, generally protein, DNA, or RNA. These alignments are used to infer evolutionary relationships via phylogenetic analysis and can highlight homologous features between sequences.
Examples: {1, 2, 3, 4, ...} is a very simple sequence (and it is an infinite sequence) {20, 25, 30, 35, ...} is also an infinite sequence. {1, 3, 5, 7} is the sequence of the first 4 odd numbers (and is a finite sequence) {4, 3, 2, 1} is 4 to 1 backwards. {1, 2, 4, 8, 16, 32, ...} is an infinite sequence where every term doubles.

Show details. Contents. Chapter 20.1 Sequence Alignment. Stephen F. Altschul and Mihai Pop. Author Information and Affiliations. Alignments are a powerful way to compare related DNA or protein sequences. They can be used to capture various facts about the sequences aligned, such as common evolutionary descent or common structural function.

What is sequence alignment?
What is multiple sequence alignment (MSA)?
Why is multiple sequence alignment important?
What happens when a sequence is aligned to a group?
A multiple sequence alignment is an alignment of n > 2 sequences obtained by inserting gaps (“‐”) into sequences such that the resulting sequences have all length L and can be arranged in a matrix of N rows and L columns where each column represents a homologous position.
