1. An RNA molecule has the following percentages of bases: A= 23%, U= 42%, C= 21%, G= 14%.
a. Is this RNA single stranded or double stranded? How can you tell?

b. What would be the percentage of bases in the template strand of the DNA that contains the gene for this RNA?

2. Anaylsis of the bases of a sample of nucleic acid yielded these percentages: A= 20%, G= 30%, C= 20%, T= 30%. Why is the sample single-stranded DNA? explain.
