Answer 1

To determine the mRNA complementary strand for the given DNA strand (ACC GTT AAT), we need to convert each DNA base to its complementary mRNA base. The base pairing rules are as follows:

- 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)

Using these rules, let's convert the DNA strand (ACC GTT AAT):

1. A (in DNA) → U (in mRNA)
2. C → G
3. C → G
4. G → C
5. T → A
6. T → A
7. A → U
8. T → A

So, for the DNA strand ACC GTT AAT, the corresponding mRNA strand would be:

- ACG CAA UUA

However, since the provided options need to be checked, let’s carefully analyze the given responses. The mRNA strand according to transcription would be:

- **UGG CAA UUA**

This response corresponds to the DNA sequence provided when transcribed into mRNA.

Therefore, the correct complementary mRNA strand is:

**UGG CAA UUA**
