In eukaryotic cells, where does protein synthesis (translation) occur?
A
In the Golgi apparatus lumen
B
On ribosomes in the cytosol or on the rough endoplasmic reticulum
C
In the nucleus on chromatin
D
Inside lysosomes
Verified step by step guidance1
Understand that protein synthesis, also known as translation, is the process where ribosomes create proteins by reading messenger RNA (mRNA) sequences.
Recall that in eukaryotic cells, ribosomes can be found either freely floating in the cytosol or attached to the rough endoplasmic reticulum (RER).
Recognize that the Golgi apparatus lumen is involved in modifying and sorting proteins after they are synthesized, not in the synthesis itself.
Note that the nucleus contains DNA and is the site of transcription (making mRNA), but translation does not occur there.
Understand that lysosomes are involved in degradation and recycling of cellular components, not in protein synthesis.
