Educational programmes all over the world are facing increasing pressure to integrate information technology in the curriculum. Knowledge of bioinformatics is at infancy in Nigeria it is therefore imperative to develop and build the capacity for high-throughput determination and computational analysis of the nucleotide base sequences of the genomes of organisms. The present communication navigated the ENTREZ Web page and downloaded sequences of Cystathionine gamma-lyase gene from Saccharomyces cerevisiae. The sequence is then represented in the five best known database formats namely Plain, FASTA, EMBL, GCG and Genebank thereby making it more visible and available for other research applications such as comparative genomic analysis, evolutionary studies, searching for and identification of regulatory elements and scanning for mutations. The present study highlights data retrieval and representation. Data retrieval is important as it provides the opportunity to engage in data mining for discovery, a convenient alternative to traditional wet laboratories, providing biological insights, and proficiency to access and use the vast repository of computational and webbased resources which are the most available information in the world today.
