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
