Answer 1

To find the complementary mRNA strand for the given DNA strand (ACC GTT AAT), we need to transcribe it by replacing each DNA base with its RNA complement:

- Adenine (A) pairs with Uracil (U) in RNA.
- Thymine (T) pairs with Adenine (A).
- Cytosine (C) pairs with Guanine (G).
- Guanine (G) pairs with Cytosine (C).

Now let's transcribe the given DNA strand:

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

So, the mRNA complementary strand for ACC GTT AAT is UGG CAA UUA.

Therefore, the correct response is:
**UGG CAA UUA**
