Enzymes copy genes and make the copying messages as RNA messages?
Context:
Histones are proteins found in the nucleus that package and order DNA into structural units. Changes to these epigenetic structures alter how DNA folds in chromosomes, making genes less or more accessible to regulatory proteins and enzymes that
copy genes into RNA messages.

@oristarA,
"RNA messages" = RNA itself
(The author is thinking of RNA as a "message" from DNA that gets translated into proteins.)
"copy genes into RNA messages" = construct sequences of RNA from sequences of DNA
