Messenger RNA (mRNA) is a subtype of RNA. An mRNA molecule carries a portion of the DNA code to other parts of the cell for processing. mRNA is created during transcription. During the ...

Johns Hopkins Medicine laboratory scientists say they have developed a potential new way to treat a variety of rare genetic diseases marked by too low levels of specific cellular proteins.

To boost those proteins, they’ve created experimental versions of a genetic “tail” that attaches to so-called mRNA molecules that churn out the proteins. A report on the researchers’ proof ...
