A T T C G G G A T A T T
A T T C G G G A T A T T

T T A T A G G G C T T A
T T A T A G G G C T T A

A A T A T C C C G A A T
A A T A T C C C G A A T

T A A G C C C T A T A A

Answer 1

To find the complementary strand of the given DNA sequence (A T T C G G G A T A T T), we need to pair each nucleotide with its complementary base:

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

Now, let's determine the complementary strand for the sequence A T T C G G G A T A T T:

1. A → T
2. T → A
3. T → A
4. C → G
5. G → C
6. G → C
7. G → C
8. A → T
9. T → A
10. A → T
11. T → A

So the complementary strand will be:

T A A G C C C T A T A A

Thus, the correct answer is:

**T A A G C C C T A T A A**
