Engineering biology through DNA’s environment

cardiac muscle cells To advance the engineering of biology at the molecular and cellular levels, the National Science Foundation (NSF) has awarded $16 million for research to characterize the regulation of gene activity and expression, and to create strategies to modify those processes without altering the DNA sequence.
Chromatin -- a combination of DNA, RNA and proteins within a cell's nucleus -- can be modified by attaching additional molecules. This can cause altered gene expression without actually ... More at https://www.nsf.gov/news/news_summ.jsp?cntn_id=296571&WT.mc_id=USNSF_51&WT.mc_ev=click
