Given the sequence of bases in the sense strand of DNA shown below, please answer the following questions.

5'-ATGTTTCCCCAGAAGAGGTATGGGAAAAAGATTTGA-3'

a. Show the sequence of bases in the messenger RNA encoded by this gene.

I'm not sure what this means. I looked up "sense strand" and found this definition:
"A DNA sequence is called "sense" if its sequence is the same as that of a messenger RNA copy that is translated into protein"

So does that mean the sequence of bases in the messanger RNA will be the same as in the strand of DNA shown, except that U will be substituted for T?

yes.

Yes, you are correct! The sequence of bases in the messenger RNA (mRNA) will be almost identical to the sense strand of DNA, with one key difference: thymine (T) is replaced by uracil (U) in mRNA.

To determine the sequence of bases in the mRNA encoded by the given gene, you can simply replace each occurrence of T with U. The sense strand of DNA provided is:

5'-ATGTTTCCCCAGAAGAGGTATGGGAAAAAGATTTGA-3'

Replacing T with U, the corresponding mRNA sequence would be:

5'-AUGUUUCCCCAGAAGAGGUAUGGGAAAAAGAUUUGA-3'
