In protein synthesis the polymerization of amino acids involves three steps. Which of the following is not involved in protein synthesis

Options

A. Termination
B. Initiation
C. Elogastion
D. Transcription

Answer

To solve the question regarding the steps involved in protein synthesis and identify which option is not involved, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Process of Protein Synthesis**:
- Protein synthesis occurs in two main stages: transcription and translation. Transcription is the process where DNA is converted into mRNA, while translation is where mRNA is used to synthesize proteins.

2. **Identify the Steps of Translation**:
- The translation process consists of three main steps:
- **Initiation**: This is where the ribosome assembles around the mRNA and the first tRNA is attached.
- **Elongation**: During this phase, amino acids are added one by one to the growing polypeptide chain.
- **Termination**: This occurs when the ribosome reaches a stop codon, signaling the end of protein synthesis.

3. **Analyze the Options**:
- The question asks for the option that is **not** involved in protein synthesis. The options typically include terms like initiation, elongation, termination, and possibly transcription.

4. **Determine the Correct Answer**:
- Since initiation, elongation, and termination are all steps involved in the translation phase of protein synthesis, the option that refers to transcription is the one that is not involved in the actual synthesis of proteins. Therefore, the correct answer is transcription.

### Final Answer:
The option that is not involved in protein synthesis is **transcription**.
