Sequence Alignment Algorithms in Bioinformatics

Bioinformatics is the subject of using computer to store,retrieve and analyze biological information. Sequence alignment is a basic problem in Bioinformatics,and its main research work is to develop rapid and effective sequence alignment algorithms. We may discover functional,structural and evolutionary information in biological sequences by sequence comparing. This paper introduces the development actuality of sequence alignment algorithms,describes variety of sequence alignment algorithm and analyses the advantages and disadvantages of them.
