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 correctly describes the function of ribosomes.

### Step-by-Step Solution:

1. **Understanding Ribosome Function**:
- Ribosomes are cellular structures responsible for protein synthesis. They play a crucial role in translating the genetic information carried by mRNA (messenger RNA) into a sequence of amino acids, which form proteins.

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

- **Option 2**: Carrying a copy of gene to cytoplasm.
- This is incorrect. Ribosomes do not carry genes; instead, mRNA, which is transcribed from DNA, carries the genetic information to the ribosome.

- **Option 3**: Contain the code for the synthesis of protein.
- This is incorrect. The ribosome itself does not contain the genetic code; the code is contained in the mRNA that is translated by the ribosome.

- **Option 4**: Determine the order of bases in the protein.
- This is incorrect. The ribosome does not determine the order of bases; it reads the mRNA sequence to assemble the corresponding amino acids.

3. **Conclusion**:
- The only correct option that describes the job performed by ribosomes during protein synthesis is **Option 1: Assembling the amino acids in a chain**.

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