The bases in the nontemplate DNA strand of a particular prokaryotic gene include 10% of thymine. What percentage of the primary transcript synthesized from this gene is uracil?

There will be 10% Uracil present in the primary transcript synthesized from the given gene.

Explanation:

The process of synthesis of RNA from DNA is called transcription. The bases present in DNA are Adenine, Guanine, Cytosine and Thymine. In the double stranded DNA the Adenine pairs with thymine and Guanine pairs with cytosine. However, in RNA the thymine is replaced by Uracil. During transcription, the RNA polymerase uses one strand of DNA as an template for assembling nucleotides on the RNA transcript. The sequence of bases on the RNA transcript is same as the sequence of bases on the Non-template strand of DNA. Only difference is, the position occupied by thymine on the non-template DNA strand is occupied by Uracil on the RNA transcript. Thus, the percentage of Uracil on the transcript will be equal to the percentage of thymine on the template strand.
