Abstract
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 tRNA(Thr) and tRNA(Pro) 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.Entities:
