Question

Quizplus · Accepted Answer

Myoclonic epilepsy and ragged red fiber disease and Leber's hereditary optic neuropathy are both examples of human disorders that appear to be transmitted extrachromosomally. Duchenne muscular dystrophy and Down syndrome are both caused by chromosomal abnormalities, cri-du-chat syndrome is caused by a deletion on chromosome 5, Leber's hereditary optic neuropathy is already mentioned in option D, and pokey chromosome syndrome and kidney cancer do not appear to be transmitted extrachromosomally. Reactive oxygen syndrome is not a known human disorder.
