First given their six-letter name by Walter Gilbert in 1978, these are very prevalent in eukaryotes and very rare in prokaryotes. Doctors have studied them to gain a better understanding of beta-thalassemia and chronic myeloic leukemia. Scientists debate whether or not they existed in early organisms, and their discovery has influenced theories on genetic evolution—scientists now believe that evolution often occurs through gene reshuffling rather than just mutations. Name these sections of precursor RNA that are not a part of messenger RNA.
