Question

choose the nucleotide sequence of the mrna strand that would be complementary to the following strand: gtagtca

Explanation:

In mRNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G). For the DNA strand GTAGTCA, each nucleotide is paired as follows: G→C, T→A (but in mRNA, A pairs with U), A→U, G→C, T→A (but in mRNA, A pairs with U), C→G, A→U. So the mRNA strand is CAUCAGU.

Answer:

CAUCAGU
