DNA acts as a templete for synthesis of :-

Options

A. DNA
B. RNA
C. Both DNA and RNA
D. Protein

Answer

To answer the question "DNA acts as a template for synthesis of:", we need to analyze the processes involved in molecular biology, particularly focusing on the role of DNA in the central dogma of molecular biology.

### Step-by-Step Solution:

1. **Understanding the Central Dogma**: The central dogma of molecular biology describes the flow of genetic information within a biological system. It outlines how DNA is transcribed into RNA, which is then translated into proteins.

2. **DNA Replication**: The first process to consider is DNA replication. During replication, DNA serves as a template to create an identical copy of itself. This means that DNA can act as a template for the synthesis of DNA.

3. **Transcription**: The second process is transcription. In transcription, DNA acts as a template to synthesize messenger RNA (mRNA). This process involves the enzyme RNA polymerase, which reads the DNA sequence and produces a complementary RNA strand.

4. **Translation**: The third process is translation, where mRNA is used as a template to synthesize proteins. However, in this case, DNA does not directly act as a template for protein synthesis; instead, mRNA does.

5. **Evaluating the Options**: Now, let's evaluate the options given in the question:
- **DNA**: Yes, DNA acts as a template for its own replication.
- **RNA**: Yes, DNA acts as a template for the synthesis of RNA during transcription.
- **Both DNA and RNA**: Since DNA acts as a template for both its own replication and for RNA synthesis, this option is correct.
- **Protein**: No, DNA does not act as a template for protein synthesis; mRNA does that.

6. **Conclusion**: The correct answer is that DNA acts as a template for the synthesis of both DNA and RNA.

### Final Answer:
DNA acts as a template for the synthesis of both DNA and RNA.
