Mapping result of hsa-mir-101-1 in G1245N library. hsa-mir-101-1 encode minor miRNA (hsa-miR-101*) at the 5p arm, ranging from nt. 11 to 32 of pre-miRNA, and major miRNA (hsa-miR-101) at the 3p arm, ranging from nt. 47 to 67. The 5p and 3p miRNAs are presented in uppercase and they individually have 10 and 22 isomiR types, each of which is labeled with read count (before normalization) and location offset. The expression level of a mature miRNA is determined by summing the read counts of all its isomiRs.
