Question

question 3 of 9
if a sequence of bases on one strand of a dna molecule is a - g - c - t - a, what is the corresponding sequence of bases on the complementary strand?
t - c - g - a - t
u - c - g - a - u
a - g - c - t - a

Explanation:

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G). Given the sequence A - G - C - T - A, we find the complementary bases one - by - one. A pairs with T, G with C, C with G, T with A and A with T.

Answer:

A. T-C-G-A-T
