Molecular characterization of a cloned dolphin mitochondrial genome.

abstract：:The nucleotide sequences of 5S rRNAs from three protozoa, Bresslaua vorax, Euplotes woodruffi and Chlamydomonas sp. have been determined and aligned together with the sequences of 12 protozoa species including unicellular green algae already reported by the authors and others. Using this alignment, a phylogenic tree o...
