Out of the two strands of DNA one is carrying genetic information for transcription and it is called

Options

A. Coding strand
B. Non template strand
C. Sense strand
D. Template strand

Answer

To answer the question, we need to understand the roles of the two strands of DNA during the process of transcription. Here’s a step-by-step solution:

### Step-by-Step Solution:

1. **Understanding DNA Structure**: DNA consists of two strands that run in opposite directions, known as antiparallel strands. Each strand is composed of nucleotides, which include a sugar, a phosphate group, and a nitrogenous base.

2. **Transcription Process**: Transcription is the process by which the information in a DNA strand is copied into a new molecule of messenger RNA (mRNA). This process is essential for gene expression.

3. **Strands of DNA**: In the context of transcription, one of the DNA strands serves as a template for mRNA synthesis, while the other strand is not directly involved in the transcription process.

4. **Identifying the Template Strand**: The strand that is used as a template for transcription is known as the **template strand**. This strand is complementary to the mRNA that is synthesized.

5. **The Coding Strand**: The other strand, which is not used as a template, is referred to as the **coding strand** or **sense strand**. This strand has the same sequence as the mRNA (except that thymine (T) in DNA is replaced by uracil (U) in RNA).

6. **Conclusion**: Therefore, the strand of DNA that carries the genetic information for transcription is called the **template strand**.

### Final Answer:
The strand of DNA that carries genetic information for transcription is called the **template strand**.
