The end-to-end distance of RNA as a randomly self-paired polymer

In this paper, we present the end-to-end distance of randomly self-paired polymers (RSPPs). We define a randomly self-paired polymer as a linear polymer each of whose monomers has a probability, f  (0

► Monomers of randomly self-paired polymer have equal probability of pairing with each other.
► We used combinatorics to explain the close proximity of RNA's ends.
► The end-to-end distance of RSPP scales as the 1/4 power of the polymer's length.
