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
Epigenetic events regulate the activities of genes without changing the DNA sequence. Different genes are expressed depending on the methyl-marks attached to DNA itself and by changes in the structure and/or composition of chromatin.
