Molecular evoution of rDNA in early diverging Metazoa: First comarative analysis and phylogenetic application of complee SSU rRNA secondary structures in Porifera.

BMC Evolutionary Biology (2008)8:69
這是一篇探討應用SSU rRNA secondary structure於海棉譜系分類的文章,作者藉由比對18S序列的length ,base composition, sybapomorphic base exchange及其secondary structure 作為estimate phylogeny的依據.看來序列的組成與結構在序列的本身外,透露著更多珍貴的演化訊息.
