Abstract: | Sequence alignment is a basic information processing method in bioinformatics and useful for discovering functional, structural, and evolutionary information in biological sequences.Typical pair-wise sequence alignment algorithms and multiple sequence alignment algorithms are described and evaluated in this paper. After analyzing difficulties in sequence alignment, a new idea-sequence alignment research base on knowledge representation system is discussed. This paper describes the definition and data processing of knowledge representation system in this sequence alignment research. |
