D. UUACGUUACCGU

Answer

To find the mRNA sequence transcribed from the given DNA template strand (AAT GCT TAG GCA), we need to follow these steps:

### Step-by-Step Solution:

1. **Identify the DNA Template Strand**: The given sequence is AAT GCT TAG GCA. This sequence is the template strand of DNA.

2. **Understand Base Pairing Rules**: During transcription, the base pairing rules are as follows:
- Adenine (A) pairs with Uracil (U) in RNA (instead of Thymine (T) in DNA).
- Thymine (T) pairs with Adenine (A).
- Cytosine (C) pairs with Guanine (G).
- Guanine (G) pairs with Cytosine (C).

3. **Transcribe the DNA Sequence to mRNA**:
- For the first base A (from AAT), it pairs with U (in mRNA).
- For the second base A (from AAT), it pairs with U (in mRNA).
- For the third base T (from AAT), it pairs with A (in mRNA).
- For the fourth base G (from GCT), it pairs with C (in mRNA).
- For the fifth base C (from GCT), it pairs with G (in mRNA).
- For the sixth base T (from GCT), it pairs with A (in mRNA).
- For the seventh base T (from TAG), it pairs with A (in mRNA).
- For the eighth base A (from TAG), it pairs with U (in mRNA).
- For the ninth base G (from TAG), it pairs with C (in mRNA).
- For the tenth base G (from GCA), it pairs with C (in mRNA).
- For the eleventh base C (from GCA), it pairs with G (in mRNA).
- For the twelfth base A (from GCA), it pairs with U (in mRNA).

4. **Combine the mRNA Bases**: After applying the base pairing rules, we get the mRNA sequence:
- mRNA = UUA CGA AUC CGU

5. **Final mRNA Sequence**: The final transcribed mRNA sequence from the DNA template AAT GCT TAG GCA is:
- **UUA CGA AUC CGU**

### Conclusion:
The mRNA sequence transcribed from the DNA template strand AAT GCT TAG GCA is **UUA CGA AUC CGU**.
