Question

If a DNA strand has a nitrogenous base sequence T, A, C, G, A, the sequence of bases on the corresponding mRNA would be ______.

विकल्प

• C, T, G, A, T

• G, U, A, C, U

• A, T, G, C, T

• A, U, G, C, U

Answer 1

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.
