                Additional comments
                The annotation for let-7 has been changed in release 5.31 of the genome annotation, so that instead of representing a mature miRNA it now represents the precursor stem loop pre-miRNA. The symbol of the annotation has been changed from CR32968 to CR42949 to reflect this change.
                Added 'mir-' prefix to be consistent with miRNA naming conventions in FlyBase, and thereby indicate the gene encodes a miRNA in its symbol.
                The three microRNAs let-7, mir-125 and mir-100 are co-transcribed as a single polycistronic transcription unit (the "let-7-Complex, let-7-C").
                Other Comments
                let-7 is required to regulate the timing of the α'/β' to α/β neuronal identity transition in the developing mushroom body, by targeting the ab transcription factor.
                let-7 is required to ensure the appropriate remodeling of the abdominal neuromusculature during the larval-to-adult transition.
                A long primary transcript comprising all the hairpin precursor sequences for mir-100, let-7 and mir-125 has been detected by RT-PCR. Overall orientation not stated: mir-100+ let-7+ mir-125+
                let-7 and mir-125 appear to be expressed from a common precursor RNA.
                mir-100, mir-125 and let-7 sequences are clustered within 800bp in 36E5--36F2.
                New annotation (CR32968) in release 3 of the genome annotation.
                Hormone induced expression of let-7 may control developmental stage transitions.
                A developmentally regulated precursor RNA is cleaved by an RNA interference-like mechanism to produce mature let-7 small temporal RNA (stRNA).
