Gene Expression
... The exciting prospect of gene expression moves above the realm of DNA and into the larger world of proteins and epigenetics. We do this by interrogating the transitional messenger RNA (mRNA) biochemistry that translates DNA sequence into proteins. This directional flow of information, from DNA -> mR ...
