A) 32; 17; 32; 19
B) 19; 32; 17; 32
C) 17; 32; 32; 19
D) 25; 25; 25; 25
E) 32; 18; 18; 32

Question

Quizplus · Accepted Answer

In DNA, adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G). Since the original strand has 32% A and 32% T, the complementary strand will also have 32% T (matching the original A) and 32% A (matching the original T). Similarly, with 18% C and 18% G in the original strand, the complementary strand will have 18% G (matching the original C) and 18% C (matching the original G).
