Question

Hello! I am working on this genetics problem and was wondering if you could check my letter d. I am not sure if this mRNA sequence is correct and would really appreciate the help. Thank you!

4. A segment of a polypeptide chain is Arg-Gly-Ser-Phe-Val-Asp-Arg. It is encoded by the following DNA: _3_ CGCTAGCTGCTTCCTT

Answer #1

Since the bottom strand is the template the mRNA synthesized would be similar to the coding strand and complementary to the template strand. So just write the sequence of coding strand by replacing T with U get the mRNA sequence.

Keep one thing in mind that RNA does not contain thymine.
