Total nucleic acids are extracted from a culture of yeast cells and are then mixed with resin beads to which the polynulceotide 5'--3' has been covalently attached. after a short incubation, the beads are then extracted from the mixture. when you analyze the cellular nucleic acids that have stuck to the beads, which of the following is most abundant?
a) dna
b) trna
c) rrna
d) mrna
