Question:
Protein synthesis in an animal cell occurs
Protein synthesis in an animal cell occurs
Updated On: Jun 7, 2022
- only on the ribosomes present in cytosol
- on ribosomes present in cytoplasm as well as in mitochondria
- only on ribosomes attached to the nuclear envelope and endoplasmic reticulum
- on ribosomes present in die nucleolus as well as in cytoplasm
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Protein synthesis takes place on ribosomes. In an eukaryotic cell ribosomes are present in cytoplasm, mitochondria and chloroplasts. So, in these places protein synthesis take place.

Prokaryotic Cells
Prokaryotic cells are single-celled microorganisms known to be the earliest on earth. Prokaryotes include Bacteria and Archaea. The photosynthetic prokaryotes include cyanobacteria that perform photosynthesis.
A prokaryotic cell contains a single membrane and therefore, all the reactions occur within the cytoplasm. They can be free-living or parasites.
Characteristics of Prokaryotic Cell:
Prokaryotic cells have different characteristic features such as:
- Lack of a nuclear membrane.
- Absence of Mitochondria, Golgi bodies, chloroplast, and lysosomes.
- Presence of genetic material on a single chromosome.
- Lack of histone proteins in the constituents of eukaryotic chromosomes.
- The cell wall is made up of carbohydrates and amino acids.
- The plasma membrane acts as the mitochondrial membrane carrying respiratory enzymes.
