Methodologies for In Vitro Cloning of Small RNAs and Application for Plant Genome(s)

Figure 2

Mass profile of human RNA. Here, the absolute mass fractions of RNAs up to 4000 nt in length are shown. The position and composition of the small RNA region, defined as that portion of the total RNA mass that is between 0 and 200 nt long are highlighted. It can be seen that, even within the small RNA region, the microRNA region lying between 18 and 26 nt, is a very small fraction of the total.
