Four nucleic-acid samples are analyzed to determine the percentages of nucleotides they contain. Survey the data in the table below to determine which samples are DNA and which are RNA, and specify whether each sample is double-stranded or single-stranded. Justify each answer (DNA and RNA can be both single and double-stranded).
