Options

A. Only on the ribosomes present in cytosol
B. On ribosomes present in cytoplasm as well as in mitochondria
C. Only on ribosomes attached to the nuclear envelope and endoplasmic reticulum
D. On ribosomes present in the nucleolus as well as in cytoplasm

Answer

Explanation

In eukaryotes membrane bound organelle mitochondria is present which has their own genetic material and 70s ribosomes helps in protein synthesis.
Protein synthesis also occurs in cytoplasm have ribosomes which serves as binding site to RNA and thus helps in protein synthesis
