Multiple nuclear pseudogenes of mitochondrial cytochrome b in Ctenomys (Caviomorpha, rodentia) with either great similarity to or high divergence from the true mitochondrial sequence.

Abstract excerpt

A fragment of the mitochondrial cytochrome b gene was studied in 13 species of the South American fossorial rodent Ctenomys using PCR with 'universal' primers and DNA sequencing after cloning. Five different groups of sequences were found, one of which corresponds to the functional mitochondrial gene (mt). The other four groups (A, B, C and D) were believed to be nuclear pseudogenes. Sequences A-C were highly...
