Translation of mRNA occurs primarily at??

[Lovelybond]

Hello

I just took #2 topscore practice test and had a question about mRNA.
The question was " Translation of mRNA occurs primarily at?"

I picked cytoplasm but the answer is ribosome.

I read the campbell biology text book it says
"The sites of translation are ribosomes, complex particles that facilitate the orderly linking of amino acids into polypeptide chains." but then the next paragraph goes "Transcription occurs in the nucleus and mRNA is then transported to the cytoplasm, where translation occurs"

Can you clarify this for me? For some reason, I'm very confused!!
Thank you.

The ribosomes which perform translation are located in the cytoplasm. I see the confusion though.. I wouldn't of known which to choose!

lol, that's a terribly worded question. I guess they could argue that translation occurs in the cytoplasm but at the ribosome, but that's pretty much a silly semantic distinction.

I'm glad I didn't bother with Topscore at this point.

There are also ribosomes located on the rough ER that produce proteins for export. Ultimately, the mRNA needs to bind to a ribosome to begin the amino acid assembly process. That ribosome could be found in the cytoplasm or the rough ER.
