When RNA is hydrolsed, there is no relationship among the quantities of different bases obtained. What does this fact suggest about the structure of RNA?

Explanation

DNA has double stranded `alpha`-helix structure. The four bases present in DNA i.e., cytosine, thymine, guanine and adenine pair up in a unique way. Cytosine always pairs up with guanine and vice versa, while thymine always pairs up with adenine and vice versa. Therefore, on hydrolysis of DNA .
No. of molecules of cytosine = No. of molecules of guanine , and, No. of molecules of adenine = No. of molecules of thymine
On the other hand, hydrolysis of RNA produces a mixture of four different bases, cytosine, uracil, guanine and adenine. In this mixture there is no relationship among the quantities of these bases. This indicates that unlike DNA, RNA has single stranded structure.
