    Concept of strings and Trees in Bioinformatics
    (ABACUS. Published by Mathematics Association of Nigeria., 2008) Oladele, Tinuke Omolewa; Bamigbola, O. M.; Gbadeyan, J. A.
    Strings have been found to be the most general medium for the representation of information. Considering the large amount of data stored in data dictionaries, databases or the massive data in genomic databases, text remains the main form of exchanging information. The representation of information from real-world problem may involve the use of many interlinked data structures. In this paper, the suffix tree data structure was used to solve the Pattern Matching problem. We present the suffix tree as an efficient data structure that provides efficient access to all substrings of a string. It is able to rapidly align sequences containing millions of nucleotides and give sufficient biological information.

    On Efficiency of Sequence Alignment Algorithms
    (African Scientist. Published by the Nigerian Society for Experimental Biology (NISEB)., 2009-03-31) Oladele, Tinuke Omolewa; Bamigbola, O. M.; Bewaji, C. O.
    The alignment of sequences is a mutual agreement of two or more sequences which exhibit their similarities where they differ. Sequence alignment is usually used to study the evolution of the sequences from a common ancestor, especially biological sequences such as protein sequences or deoxyribonucleic acid (DNA) sequences. Sequence alignment can also be used to study the evolution of languages and the similarity between texts. In this paper, we discuss sequence alignments for finding similarities between sequences, homologues (relatives) on a gene or gene-product in genomic databases. This information is useful for answering a variety of biologically related questions.
