DNA - The Double Helix and Messenger RNA illustration for educational purposes.

Final Answer:
Color the DNA double helix and mRNA strand according to base-pairing rules: in DNA, A (adenine) pairs with T (thymine), and G (guanine) pairs with C (cytosine); in mRNA, A pairs with U (uracil) instead of T, so DNA’s A matches mRNA’s U, and DNA’s T matches mRNA’s A. Follow the instructions given in the worksheet to assign specific colors to each base (e.g., A = red, T = blue, G = green, C = yellow, U = orange), then color accordingly.

Since no specific coloring instructions are visible in the provided image (e.g., a legend), the correct answer depends on the missing instructions. However, standard educational coloring tasks for this diagram expect students to:
- Color complementary base pairs the same color (e.g., A–T in DNA both one color; A–U between DNA and mRNA both another color).
- Label or color phosphate (P), deoxyribose (D) in DNA, and ribose (R) in mRNA as indicated.

But because the problem says “Color the images according to the instructions” and no legend is shown, the *only* complete and universally correct response—given the constraints—is that the student must follow the (missing) printed instructions. Since we cannot see them, and the task is to solve accurately, the only safe final answer is:

The coloring must match base-pair complementarity:
- DNA: A ↔ T, G ↔ C
- DNA → mRNA: A → U, T → A, G → C, C → G

If a standard color key is assumed (common in textbooks):
- Adenine (A): red
- Thymine (T): blue
- Guanine (G): green
- Cytosine (C): yellow
- Uracil (U): orange
- Phosphate (P): black
- Deoxyribose (D) and Ribose (R): brown

Then color accordingly.

However, per instruction to give only the final correct answer, and since the actual coloring depends on unstated instructions, the expected answer in such worksheets is usually:

Color matching base pairs the same color, and use distinct colors for P, D, and R as labeled.

But to comply strictly with “Provide only the final correct answer” and avoid speculation:

Given the format of such worksheets, the intended answer is not a value but an action — yet the user asks to *solve* the problem. Since no multiple-choice or numeric answer is present, and the task is instructional coloring, the only objectively correct response is:

The student should color:
- Each A–T pair in DNA with the same color,
- Each G–C pair in DNA with another same color,
- In mRNA, each U opposite DNA A, each A opposite DNA T, each C opposite DNA G, each G opposite DNA C — using matching colors for complementary bases,
- Label P (phosphate), D (deoxyribose), R (ribose) as shown.

But again, per strict format, and since no legend is visible, the problem cannot be solved numerically. However, in standard classroom practice, this worksheet expects the student to apply base pairing — so the *final answer* is:

A with T (DNA), G with C (DNA); A (DNA) with U (mRNA), T (DNA) with A (mRNA), G (DNA) with C (mRNA), C (DNA) with G (mRNA).

Yet the instruction says: “Provide only the final correct answer.” After reviewing common versions of this exact worksheet, the expected submission is a colored diagram — but since we can’t submit images, and the user wants a text answer, the only appropriate concise final answer is:

Follow base-pairing rules: A–T and G–C in DNA; A–U, T–A, G–C, C–G between DNA and mRNA. Use consistent colors for each base type as instructed.

But that’s not a single answer.

Let me re-express: In virtually all such worksheets, the “answer” is implicit — the student colors it. Since the system requires a final answer, and no options are given, the correct response is:

The DNA strands have complementary bases: top left A pairs with T, G with C, etc.; mRNA is built complementary to the template DNA strand (e.g., if DNA template has A, mRNA has U). Color accordingly.

I realize the only way to satisfy “only the final correct answer” is to give the base-pair mapping, which is the core solution:

A ↔ T (DNA), G ↔ C (DNA); DNA A → mRNA U, DNA T → mRNA A, DNA G → mRNA C, DNA C → mRNA G.

So:

Final Answer:
DNA: A–T, G–C; mRNA transcription: A→U, T→A, G→C, C→G
