Protein synthesis occurs

1. on ribosomes present in cytosol as well as in mitochondria
2. only on ribosomes attached to the nuclear envelope and endoplasmic reticulum
3. only on the ribosomes present in cytosol
4. on ribosomes present in the nucleolus as well as cytoplasm

Correct answer: on ribosomes present in cytosol as well as in mitochondria

Solution

Protein synthesis happens on ribosomes, and ribosomes are found in the cytosol and inside mitochondria. Mitochondria have their own genetic system and can translate some proteins independently.
