The Epigenetic Lnc
Kevin V. Morris | Oct 1, 2012
Long non-protein-coding RNA (lncRNA) sequences are often transcribed from the opposite, or antisense, strand of a protein coding gene. In the past few years, research has shown that these lncRNAs play a number of regulatory roles in the cell. For exa
