In transcription

Options

A. The total DNA of an organism gets duplicated
B. Only a segment of DNA is copied into RNA
C. Only one of the strands of DNA is copied into RNA
D. Both (2) and (3) occur

Answer

**Step-by-Step Solution:**

1. **Understanding Transcription:**
- Transcription is the process through which RNA is synthesized from a DNA template. It is a crucial step in the expression of genes.

2. **Analyzing the Options:**
- **Option A:** "The total DNA of an organism gets duplicated."
- This statement is incorrect. During transcription, only specific segments of DNA are transcribed into RNA, not the entire DNA.

- **Option B:** "Only a segment of DNA is copied to RNA."
- This statement is correct. Transcription involves copying a specific segment of DNA into RNA.

- **Option C:** "Only one of the strands of DNA is copied into RNA."
- This statement is also correct. In transcription, only one strand of the DNA double helix serves as the template for RNA synthesis.

- **Option D:** "Both 2 and 3."
- Since both options B and C are correct, this option is also correct.

3. **Conclusion:**
- The correct answer is Option D, which states that both statements 2 and 3 are correct.

**Final Answer:**
- The correct option is **D** (Both 2 and 3).
