Studying miRNA target sites in the LTR of a one-LTR molecular HIV-1 clone. By pairing to microRNA responsive elements (mREs) on target mRNAs, miRNAs play gene-regulatory roles, producing remarkable changes in several physiological and pathological processes. These structures are then recognized and processed by RNase endonuclease III (Dicer) to create miRNA duplexes (Fabian and Sonenberg, 2012). The assay, however, is still completely functional for the sequence for which it was originallyAntagomir. RNA was isolated and. Because miRNAs are so small (19-22nt), it is not possible to design primers for them using conventional primer design software. Similar with the above approach, Marsico et al.
