D. 4)5 - UACGUACGUACG - 3.

Answer

To solve the problem of determining the RNA transcribed from the given DNA segment, we will follow these steps:

### Step-by-Step Solution:

1. **Identify the DNA Strands**:
- We have two strands of DNA provided:
- Template Strand: 3' - ATGCATGCATGC - 5'
- Coding Strand: 5' - TACGTACGTACG - 3'

2. **Understand the Transcription Process**:
- Transcription is the process of synthesizing RNA from a DNA template.
- RNA is synthesized in the 5' to 3' direction, using the template strand as a guide.

3. **Determine the RNA Sequence**:
- The RNA sequence is complementary to the template strand and will replace thymine (T) with uracil (U).
- The template strand is read from 3' to 5', so we will write the RNA from 5' to 3'.

4. **Transcribe the RNA**:
- The template strand (3' - ATGCATGCATGC - 5') will be transcribed as follows:
- A (from the template) pairs with U (in RNA)
- T (from the template) pairs with A (in RNA)
- G (from the template) pairs with C (in RNA)
- C (from the template) pairs with G (in RNA)
- Following this pattern for the entire template strand:
- 3' - A T G C A T G C A T G C - 5' (Template)
- 5' - U A C G U A C G U A C G - 3' (RNA)

5. **Final RNA Sequence**:
- The final RNA sequence transcribed from the template strand is:
- 5' - UACGUACGUACG - 3'

6. **Select the Correct Option**:
- Compare the transcribed RNA sequence with the provided options to find the correct one.
