Comparison of genetics, phenotypic and behavioral properties of eubacteria and archaebacteria

Abstract

Background: The genome of the bacteria has considerable diversity and change over the time. With the advancement of bioinformatics science possibility of the vast comparison to living organisms has risen. In this study we compared some of the genetic, phenotypic and behavioral properties of archaebacteria and eubacteria. Methods: Genomic Information of 286 species of archaebacteria and 122 species of eubacteria were collected from the NCBI ) National Center for Biotechnology Information( site. Mean of gene size, gene number, protein number and  C + G content compared in the two groups of archaebacteria and eubacteria.  Association of genomic characterization of bacteria with several other characteristics were analyzed using SPSS statistical software version 19. Results: There was significant association between means discrepancy in two group. The genome size of eubacteria and archaebacteria have significant association with some of the characteristics of bacteria, such as the C + G content, the number of proteins, genes and habitats of the bacteria. As well as there was significant association between genome size and features such as number of pseudogene, mobility and type of breathing in eubacteria but not in archaebacteria. Conclusion: Many characteristics  of eubacteria and archaebacteria are significantly associated with genomic properties. Comparison genomics of bacteria will help in identification of evolutionary origins as well as differences between different categories of bacterial.
