Question

complete the dna molecule based on the rules for complementary base pairing drag labels to their correct position on the image

Explanation:

Step1: Recall DNA base pairing rules

In DNA, adenine (A) pairs with thymine (T), and cytosine (C) pairs with guanine (G).

Step2: Pair each base

• For the base "A" (adenine) in the DNA structure, its complementary base is "T" (thymine).
• For the base "T" (thymine), its complementary base is "A" (adenine).
• For the base "C" (cytosine, represented by the circular structure), its complementary base is "G" (guanine).
• For the base "G" (guanine), its complementary base is "C" (cytosine).

Answer:

• Pair "A" with "T", "T" with "A", "C" with "G", "G" with "C" (by dragging the labels to their respective complementary base positions as per the DNA base - pairing rules).
