Interactive DNA base pairing exercise for learning complementary nucleotide sequences.

The task is about base pairing in DNA. In DNA, bases pair up in a specific way:

- Adenine (A) always pairs with Thymine (T)
- Cytosine (C) always pairs with Guanine (G)

Looking at the left side of the DNA strand, we have these bases in order from top to bottom:
T, A, C, A, G, T, T, A, C

Now, let’s match each one with its correct partner:

1. T → pairs with A
2. A → pairs with T
3. C → pairs with G
4. A → pairs with T
5. G → pairs with C
6. T → pairs with A
7. T → pairs with A
8. A → pairs with T
9. C → pairs with G

So the missing bases on the right side, from top to bottom, should be:
A, T, G, T, C, A, A, T, G

Final Answer:
A, T, G, T, C, A, A, T, G
