    Clustering of tRNA genes in Paracentrotus lividus mitochondrial DNA (1988)
    Springer
    Current genetics 13 (1988), S. 91-96 
    Details
    ISSN: 1432-0983
    Keywords: mtDNA ; Sea urchin ; Gene organization ; tRNA gene clustering
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary We have determined the base sequence of the restriction fragment Bam1-2 (3,593) of Paracentrotus lividus (sea urchin) mtDNA. This fragment contains, in addition to genes previously identified (part of the 12S rRNA, ND1 and part of the ND2 mRNA), a cluster of 15 tRNA genes located between the 12S and ND1 genes. Also to be found in the tRNA gene cluster, between the tRNAThr and tRNAPro genes, is a sequence of 134 bp which constitutes the only non-coding region of this DNA so far identified. The distinctive organization of the tRNA genes and the extreme size reduction of the non-coding region suggest the existence of unique mechanisms for the regulation of gene expression in this organism.

    Faithful and highly efficient RNA synthesis in isolated mitochondria from rat liver (1988)
    Springer
    Current genetics 14 (1988), S. 477-482 
    Details
    ISSN: 1432-0983
    Keywords: Non-growing cells ; Isolated organelles ; RNA synthesis
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Isolated rat liver mitochondria in the presence of an appropriate incubation buffer are able to support DNA transcription and RNA processing in a way qualitatively and quantitatively similar to that used by intact cells. This system is also able to synthesize an RNA species of 155–175 nucleotides which probably corresponds to the 7S RNA, a type of RNA found so far only in growing cells. The role of this RNA in the mitochondrial replication and transcription processes, in relation to the cell metabolism, is discussed.
