A group II intron in the Neurospora mitochondrial coI gene: nucleotide sequence and implications for splicing and molecular evolution.

abstract：:We have measured the amount of 5S-ribosomal DNA in the genomes of Xenopus laevis, Triturus cristatus carnifex and Ambystoma mexicanum, three species of Amphibians which have widely different C-values. Our best estimate is that these organisms have about 24,000, 32,000 and 61,000 5S-genes per haploid genome respectivel...
