One strand of the DNA molecule contains 32% of nucleotides with adenine. What amount (%) of nucleotides

One strand of the DNA molecule contains 32% of nucleotides with adenine. What amount (%) of nucleotides with thymine will be contained in the mRNA molecule?

A tricky task.

The answer is 0%.

One of the main differences between DNA and RNA, in addition to different pentoses (deoxyribose and ribose), is the different qualitative composition of nitrogen bases.

For DNA, these are adenine, guanine, thymine, and cytosine, while for RNA, these are adenine, guanine, cytosine, and uracil.

Therefore, the mRNA molecule will contain 32% of the nucleotides with uracil. Thymine, on the other hand, cannot be present in any of the main types of ribonucleic acids.
