Protein synthesis in living cells is called called,

Options

A. Transcription
B. Translation
C. Replication
D. Duplication

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the name of the process by which proteins are synthesized in living cells.

2. **Identifying the Options**: The options provided are:
- A. Transcription
- B. Translation
- C. Replication
- D. Duplication

3. **Analyzing Each Option**:
- **Transcription**: This is the process where the genetic information from DNA is copied into messenger RNA (mRNA). While it's an important step in the overall process of protein synthesis, it specifically refers to mRNA synthesis, not the actual synthesis of proteins.

- **Translation**: This is the process where the information carried by mRNA is used to assemble amino acids into a protein. This is the actual step where protein synthesis occurs, making this option relevant to the question.

- **Replication**: This refers to the process of making an exact copy of DNA. It does not involve protein synthesis, so this option is incorrect.

- **Duplication**: This term generally refers to the doubling of genetic material, particularly DNA. It does not pertain to the synthesis of proteins, making this option incorrect as well.

4. **Conclusion**: The correct answer to the question "Protein synthesis in living cells is called" is **Translation**.

**Final Answer**: Translation
