Answer 1

To find the complementary mRNA strand for the given DNA strand, you need to replace each DNA base with its complementary RNA base:

- A (adenine) pairs with U (uracil) in RNA
- T (thymine) pairs with A (adenine)
- C (cytosine) pairs with G (guanine)
- G (guanine) pairs with C (cytosine)

Given the DNA strand: **ACC GTT AAT**

The complementary mRNA strand would be created as follows:

- A → U
- C → G
- C → G
- (space)
- G → C
- T → A
- T → A
- (space)
- A → U
- A → U
- T → A

So, the complementary mRNA strand is: **UGG CAA UUA**.

Thus, the correct response is:

**UGG CAA UUA**.
