Using powerful new sequencing technologies, investigators can now catalog every rna molecule made by a cell and determine at what quantities these rnas are present. the graphs show the relative quantities of two different mrnas—one transcribed from gene x, the other from gene y—in two different cell types. which most likely encodes a housekeeping protein?

choose one:

a. both genes
b. neither gene
c. gene b only
d. gene a only
