Translation
Multiple Choice
In eukaryotic cells, translation (protein synthesis) occurs in which part of the cell?
A
On ribosomes in the cytoplasm, including those bound to the rough endoplasmic reticulum
B
In the nucleus on chromatin
C
In the Golgi apparatus during protein sorting
D
In the mitochondria for all cellular proteins
Verified step by step guidance1
Recall that translation is the process of synthesizing proteins from messenger RNA (mRNA) templates.
Understand that in eukaryotic cells, translation primarily occurs on ribosomes, which can be free in the cytoplasm or attached to the rough endoplasmic reticulum (RER).
Recognize that the nucleus is the site of transcription (DNA to RNA), not translation, so translation does not occur on chromatin inside the nucleus.
Note that the Golgi apparatus is involved in modifying, sorting, and packaging proteins after they are synthesized, but it is not the site of translation.
Remember that mitochondria have their own ribosomes and can translate some proteins encoded by mitochondrial DNA, but the majority of cellular proteins are synthesized on cytoplasmic ribosomes.
