Answer :
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.
