Answer 1

To find the mRNA complementary strand for the given DNA strand, we need to follow the base pairing rules, where adenine (A) pairs with uracil (U) in RNA (instead of thymine in DNA), cytosine (C) pairs with guanine (G), guanine (G) pairs with cytosine (C), and thymine (T) pairs with adenine (A).

Given the DNA strand:
ACC GTT AAT

The complementary mRNA strand would be:
- A pairs with U
- C pairs with G
- C pairs with G
- G pairs with C
- T pairs with A
- T pairs with A
- A pairs with U
- T pairs with A

Putting it all together, the mRNA strand becomes:
UGG CAA UUA

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