Updated On: Jul 12, 2022
- ribosomes which occur on nuclear membrane and E.R.
- ribosomes of only cytosol
- ribosomes of only nucleolus and cytosol
- ribosomes of only mitochondria and cytosol.

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Ribosomes present in nuclear membrane and endoplasmic reticulum take part in protein synthesis. Two or more ribosomes simultaneously engaged in protein synthesis on the same wRNA strand forming polyribosomes. The ribosome functions as a template, bringing together different components required for protein synthesis.

Cell: The Unit of Life
- A cell is derived as the functional and structural unit of life. Every cell is surrounded by a cell membrane that dissects the external and internal environments of the cell. The interior environment of a cell is called the cytoplasm.
- It carries cellular machinery and structural elements. The nucleus is present in the center of the cell, which includes all the hereditary information of an organism. Some of the molecules present in the cell are protein, carbohydrates, starch, and sugar.
