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.
Naime, problem s microRNA je taj da ne možemo koristiti postojeću  tehnologiju baziranu na DNA kako bismo ih pouzdano detektirali, jer oni su vrlo kratki dijelovi nukleotida, mnogo manji od DNA.
