A diagram of two kinds of RNA doing their thing inside a cell (which is converting instructions from DNA into some kind of protein that a cell uses to do something.
Since this illustration originally came from an article called, “mRNA-Based Protein Replacement Therapy for the Heart,” you can kind of guess what sort of something this mRNA-produced protein is doing: replacing tiny bits of heart.
This is what a medical success looks like.
From the description on Wikimedia Commons, where I found this image (which is the left half of a side-by-side comparison):
Comparing uptake of RNA and modRNA by the cell: (Left) modRNA delivery does not cause any activation of immune response and escapes RNase degradation. (Right) mRNA triggers activation of TLR7/8 and is prone to degradation by RNase.
