The i-RNA molecule contains 13% adenyl, 27% guanyl and 39% uracil nucleotides. Determine the ratio of all types

The i-RNA molecule contains 13% adenyl, 27% guanyl and 39% uracil nucleotides. Determine the ratio of all types of nucleotides in the DNA with which this m-RNA was transcribed.

100- (13 (A) +27 (D) +39 (Y)) = 21 (C) A + T = 52%; H + C = 48%
Answer: A-26%; T-26%; G-24%; C-24%.
