Remember that mRNA is transcribed from DNA, and the following rules apply:
* Adenine (A) in DNA pairs with Uracil (U) in RNA.
* Guanine (G) in DNA pairs with Cytosine (C) in RNA.
* Cytosine (C) in DNA pairs with Guanine (G) in RNA.
* Thymine (T) in DNA pairs with Adenine (A) in RNA.
Once you provide the DNA sequence, I can give you the transcribed mRNA sequence.
