Answer 1

To transcribe the DNA sequence AAT - CGA - ACT into mRNA, you need to replace Thymine (T) with Uracil (U) and use the complementary RNA base pairs: Adenine (A) pairs with Uracil (U), Thymine (T) pairs with Adenine (A), Cytosine (C) pairs with Guanine (G), and Guanine (G) pairs with Cytosine (C).

The transcription would go as follows:

1. AAT (DNA) → UUA (mRNA)
2. CGA (DNA) → GCU (mRNA)
3. ACT (DNA) → UGA (mRNA)

So the mRNA sequence is: UUA - GCU - UGA.

Thus, the correct response is:
**UUA - GCU - UGA**
