Structural Patching Fosters Divergence of Mitochondrial Ribosomes.

abstract：:We review all instances in which the nuclear 5S rRNA genes of fungi, protist, nematode, and arthropod species have been reported to be linked to the tandemly repeated units of the rDNA, trans-spliced leader, and histone multigene families. The evolution of these gene arrangements is analyzed by mapping them to indepen...
