Synthesis of DNA from RNA is explained by

Options

A. central dogma reverse
B. reverse transcription
C. teminism
D. all of these.

Explanation

### Step-by-Step Solution:

1. **Understanding the Central Dogma of Molecular Biology**:
- The central dogma describes the flow of genetic information within a biological system. It states that DNA is transcribed into RNA, which is then translated into proteins.

2. **Identifying the Reverse Process**:
- The question asks about the synthesis of DNA from RNA, which is the reverse of the central dogma. In this case, RNA is used to synthesize DNA.

3. **Naming the Process**:
- The process of synthesizing DNA from RNA is known as **reverse transcription**. This term indicates that the normal flow of information (DNA to RNA) is being reversed.

4. **Alternative Terminology**:
- Reverse transcription is also referred to as **Teminism**, named after Howard Temin, who contributed to the understanding of this process.

5. **Context of the Process**:
- This process is particularly observed in certain viruses, especially retroviruses, which have single-stranded RNA. When these viruses infect a host, their RNA can be reverse transcribed into DNA, which can then integrate into the host's genome.

6. **Conclusion**:
- Therefore, the synthesis of DNA from RNA is explained by reverse transcription, which is also known as Teminism. The answer to the question is that it can be referred to as reverse central dogma, reverse transcription, and Teminism.

### Final Answer:
The synthesis of DNA from RNA is explained by **reverse transcription** (also known as **Teminism**), which is part of the **reverse central dogma of molecular biology**.
