Abakyzed Reoeats And Constructed A Repeats ' Database Of Prokaryonea

This paper mainly analyzed the collection and classification and constructing a database of the repetitive sequences of the Prokaryonea. In the first two chapters, we give a summary of Bioinformatics and the Eukaryonta' s repeats, respectively. They are the general bases of our concrete work (chapter 3 to chapter 5).In the third chapter, we collected all repetitive sequences of the Prokaryonea by the strategy of " short but many, long but few" . We analyzed forty-one bacteria' DNA sequences, write down all repeats' positions and repetitive times. In addition, we statisticed the containment, the most repetitive times and the most long sequence of the forty-one bacteria.In the forth chapter, classification of the repeats which we have collected were emphasized and analyzed. On the basis of the region of gene that repeats are dropped in, or the obvious feature-structure of the repeats, or repetitive times and repetitive length, blocks and strings are classed.In the fifth chapter, we constructed a repetitive sequences' database of the Prokaryonea. Designed the flat file of the database and made it concreted in the Oracle.
