human mitochondrial dna (mtdna) is 16,569 base pairs (bp) in length, coding for 37 genes. during the course of evolution, nearly all the genes expressing ribosomal proteins and ribosomal rnas (rrna) genes have been transferred from the mitochondria to the nucleus. however, mitochondrial dna contains two ribosomal rnas genes (12s and 16s), which have not yet transferred to the nucleus. these two...
