The strand of DNA which is complimentary to the template strand is

Options

A. Antisense strand
B. Noncoding strand
C. Sense strand
D. Both 1 & 2

Answer

To solve the question regarding the strand of DNA that is complementary to the template strand, we can break it down step by step:

### Step-by-Step Solution:

1. **Understanding DNA Structure**:
- DNA consists of two strands that run in opposite directions (antiparallel). One strand serves as the template for transcription, while the other strand is complementary to it.

2. **Identifying the Template Strand**:
- The template strand is the one that is used during transcription to synthesize mRNA. This strand is also known as the non-coding strand or antisense strand.

3. **Complementary Strand**:
- The strand that is complementary to the template strand is known as the coding strand or sense strand. This strand has the same sequence as the mRNA (except for the substitution of uracil for thymine).

4. **Analyzing the Options**:
- Option 1: Antisense Strand - This is the template strand, not the complementary one.
- Option 2: Non-Coding Strand - This also refers to the template strand.
- Option 3: Sense Strand - This is the correct answer as it is the strand complementary to the template strand.
- Option 4: Both One and Two - This is incorrect since both options refer to the template strand.

5. **Conclusion**:
- The strand of DNA that is complementary to the template strand is the **sense strand** (Option 3).

### Final Answer:
The strand of DNA which is complementary to the template strand is the **sense strand**.
