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 19 2 34 16 15 0 35 3 30 21 0 26 23 4 33 16 34 0 17  A.  Which tube MOST likely contains rotavirus? (2 points) B.  Briefly explain your reasoning, including both your selection of DNA vs. RNA and double stranded vs. single stranded in your answer. (4 points)
