Novel CRISPR approach uses an on-off switch for epigenome editing
Reversible genome-wide epigenetic editing may be possible with a new approach using cellular memory to silence gene expression...
Gene expression is the process of converting the information contained in a gene into the gene product. The DNA of the gene is first transcribed into RNA, which is then either translated into a protein or remains as an RNA molecule. The expression level of a particular gene can be turned ’up’ or ‘down’ in different cells at different times, as required.
