Multiple Choice
In eukaryotic cells, what is the primary location where translation of mRNA into protein occurs?
A
Inside the nucleus on chromatin
B
Within lysosomes where mRNA is decoded
C
In the Golgi apparatus lumen
D
On ribosomes in the cytosol (including those bound to the rough endoplasmic reticulum)
Verified step by step guidance1
Understand that translation is the process by which the genetic code carried by mRNA is decoded to produce a specific polypeptide or protein.
Recall that in eukaryotic cells, translation does not occur inside the nucleus because the nucleus is where transcription (mRNA synthesis) happens, not translation.
Identify the cellular structures involved in translation: ribosomes are the molecular machines that read mRNA sequences and assemble amino acids into proteins.
Recognize that ribosomes can be free in the cytosol or bound to the rough endoplasmic reticulum (ER), both serving as sites for translation.
Conclude that the primary location for translation of mRNA into protein in eukaryotic cells is on ribosomes in the cytosol, including those attached to the rough ER.
