It has also been considered as a useful target molecule to study molecular mechanisms involved in the control of transcription and replication process (2). Gene contein of the animal mtDNA is highly conserved but in spite of this gene rearrangements have widely occur during mtDNA evolution. The more striking examples are founded in invertebrates (3, 4, 5). Most of the changes involved tRNA genes relocations, however there are a number of examples where complete segments have been inverted and have been considered as useful markers to clarified phylogenetic relationships (6).In this work we report partial sequences of the shrimp Penaeus notialis mtDNA. This brings new information about genome organization of a group where knowloged is limitated. Copyright 1996 Elfos Scientia
