However, the problem with microRNAs is that we cannot use existing DNA-based technology to detect them in a reliable way, because they are very short sequences of nucleotides, much smaller than DNA.
Az a bökkenő a mikroRNS-ekkel, hogy megbízható kimutatásukra a DNS-alapú jelenlegi technikák nem alkalmasak, mert a mikroRNS-ek  igen rövid nukleotidszakaszok, a DNS-nél sokkal rövidebbek.
