Answer: No

Explanation:

DNA is double standard and contains 4 bases Adenine, cytosine, guanine and thymine. Base pairing occurs in DNA. Chargaff's rule state that Adenine always pairs with thymine, and Cytosine always pairs with guanine, therefore the amount of Adenine is always equal to thymine and cytosine is always equal to quanine in a DNA molecule.

But Chargaff's rule only applies to DNA and not RNA. This is because RNA is single-stranded, and thus, base pairing is absent also RNA replaces thymine with Uracil. There's no correlation between base pair in RNA.

The answer is No.
