The function of polysome in bacterial cell is to

Options

A. Translate the mRNA into protein
B. Store reserve food materials
C. Sythesize pigments
D. Help in buoyancy

Answer

**Step-by-Step Solution:**

1. **Understanding Polysomes**: Polysomes, also known as polyribosomes, are structures formed by multiple ribosomes that are simultaneously translating a single mRNA molecule. In bacterial cells, which are prokaryotic, these structures play a crucial role in protein synthesis.

2. **Function of Ribosomes**: Ribosomes are the cellular machinery responsible for translating mRNA into proteins. They read the sequence of the mRNA and assemble the corresponding amino acids to form a polypeptide chain.

3. **Translation Process**: During translation, ribosomes bind to the mRNA at the start codon. As one ribosome moves along the mRNA, it synthesizes a polypeptide chain. Other ribosomes can attach to the same mRNA strand, forming a polysome, which allows for multiple copies of a protein to be synthesized simultaneously.

4. **Role of Polysomes in Bacteria**: In bacterial cells, polysomes enhance the efficiency of protein synthesis. Since bacteria do not have a nucleus, the processes of transcription (mRNA synthesis) and translation (protein synthesis) occur simultaneously in the cytoplasm. Polysomes enable rapid production of proteins by allowing multiple ribosomes to translate the same mRNA strand at once.

5. **Conclusion**: The primary function of polysomes in bacterial cells is to translate mRNA into proteins, facilitating efficient protein synthesis.

**Final Answer**: The function of polysomes in bacterial cells is to translate the mRNA into proteins.
