| mirbaseSEQUENCE {mirbase.db} | R Documentation |
mirbaseSEQUENCE is an R object that provides mappings between microRNA identifiers and their precursor sequence (stem-loop).
Each microRNA identifier maps to a unique character string
representing the precursor (stem-loop) sequence of the microRNA.
A graphical representation of the folded sequence can be found by
using mirbaseHAIRPIN.
