You are a research assistant in a lab that studies nucleic acids. Your advisor gave you four tubes for analysis. Each of these tubes differs in its contents by the source of its nucleic acids: mouse cytoplasm (single-stranded RNA), yeast nuclei (double-stranded DNA), rotavirus (double-stranded RNA), and parvovirus (single-stranded DNA). The approximate nucleotide base composition of each sample is given in the table below.   Tube A C U T G 1 32 17 0 32 17 2 34 16 15 0 35 3 30 46 0 10 23 4 33 16 25 0 17 Which tube most likely contains yeast nuclei?
