Solution
If a DNA strand has a nitrogenous base sequence T, A, C, G, A, the sequence of bases on the corresponding mRNA would be A, U, G, C, U.
Explanation:
During transcription, each DNA base pairs with its RNA complement: A → U, T → A, C → G, G → C. So the DNA sequence T, A, C, G, A gives mRNA A, U, G, C, U.
