During protein synthesis , ribosome is found to be performing which of the following jobs ?

Options

A. assemble amino acids in a chain
B. carry a copy of gene to cytoplasm
C. contain the code for the synthesis of a protein
D. determine the order of bases in the protein

Answer

To solve the question regarding the role of ribosomes during protein synthesis, we will analyze each option provided and determine which one accurately describes the function of ribosomes.

### Step-by-Step Solution:

1. **Understanding Protein Synthesis**:
- Protein synthesis occurs through a process called translation, where ribosomes play a crucial role.

2. **Analyzing the Options**:
- **Option 1**: Assemble amino acids in a chain.
- This option is correct. Ribosomes facilitate the assembly of amino acids into a polypeptide chain based on the sequence of codons in the mRNA.

- **Option 2**: Carry a copy of gene to cytoplasm.
- This option is incorrect. The messenger RNA (mRNA) carries the genetic information from the DNA in the nucleus to the ribosome in the cytoplasm, not the ribosome itself.

- **Option 3**: Contain the code for the synthesis of protein.
- This option is also incorrect. The ribosome does not contain the code; rather, it reads the code present in the mRNA to synthesize proteins.

- **Option 4**: Determine the order of bases in the protein.
- This option is incorrect. The ribosome does not determine the order of bases; it translates the mRNA sequence into a corresponding amino acid sequence.

3. **Conclusion**:
- The only correct option is **Option 1: Assemble amino acids in a chain**. This accurately describes the primary function of ribosomes during protein synthesis.

### Final Answer:
The ribosome is found to be performing the job of assembling amino acids in a chain during protein synthesis.
