| molecularNote | Sequence for the mature 21 nt sequence was replaced by a neomycin/lacZ construct leaving the rest of the transcript sequence intact. Absence of transcript for the deleted 21 nt was confirmed by PCR. A neighboring miRNA and the gene in which the two micro RNAs are "embedded" are both transcribed normally. |
