What Is Aligning Dna

Sequence alignment is a way of arranging protein (or DNA) sequences to identify regions of similarity that may be a consequence of evolutionary relationships between the sequences.

How do you do sequence alignment?

1. Click on the Align link in the header bar to align two or more protein sequences with the Clustal Omega program.
2. Enter either protein sequences in FASTA format or UniProt identifiers into the form field (Figure 39)
3. Click the ‘Run Align’ button.

How long does sequence alignment take?

For instance, the sequencing program MUSCLE can usually handle large data sets with a premium on accuracy. For some perspective, I can usually align ~750 sequences of 1000 nucleotides each in about an hour using MUSCLE. For aligning a large number of sequences, you must have sufficient computer memory and storage.
