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. in an experiment, researchers measured the relative quantities of two different mrnas—one transcribed from gene a, the other from gene b—in two different cell types. gene b is expressed in both the liver and the brain whereas gene a is expressed in the brain but not in the liver. which most likely encodes a housekeeping protein?

choose one:

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