Explanation:
Answer:
The correct answer to the question is: 1) free in the cytoplasm.
Explanation:
- Ribosomes are responsible for synthesising polypeptide chains by the process of translation from mRNA or messenger Ribonucleic Acid.
- They are found free in the cytoplasm or remain bound to the Endoplasmic Reticulum (ER) to form the Rough Endoplasmic Reticulum (RER).
- The cytoplasmic proteins are synthesised by the free ribosomes.
- The membrane proteins, secretory proteins and the organelle specific proteins are synthesised by the Ribosomes located on the Endoplasmic Reticulum.
- This is because these proteins need to be translocated to the target organs through vesicles that buds out of the ER and and the Golgi bodies.
- As the luciferase polypeptide is located in the cytoplasm, it is synthesised by the free ribosomes present in the cytoplasm.
The answer is the nucleus
