translation

whats the best anwer for the question ''where does translation take place?''
Is it simply ''in the cytoplasm''or ''in the ribosomes''or ''ribosomes in the cytoplasm''? :?

"ribosomes in the cytoplasm" would be correct but to be precise, It happens in the rough endoplasmic reticulum, a series of membrane-built pipes with connections to the nucleus and to be more precise, it occurs on the ribosomes which line the reticulum.

hmmm....I would say in the ribosomes cause u have mitochondrial rRNA(and mitochondrial DNA ) so u have mitochondrial translation system. Mt rRNA are smaller than ones from cytoplasm but they have important role in synthesis of some mt proteins.
If u want to know more check here

'In the ribosomes' is a general answer. And I too think its correct.

The correct answer is in the ribosoms.
The cytoplasm-deffinetly not correct
Ribosoms in the cytoplasm- not correct because there are also rybosoms attached to the rough ER and nuclear membrane.
About the mithocondrial ribosoms: They resemble very much those of archea: size just like bacteria, but rRNA 16S in small subunit of ribosoms resembles very much 18S rRNA in the small subunit of eukaryotic cells. Another resemblence between mitocondria and archea is that they both have introns.

Yup, I'd say the same...Ribosomes..and they're located in Reticulum Endoplasm which is called Granullar RE (b'coz it contains ribosomes)

Ribosoms are located both in the cytoplasm and the rough ER. And they are ON the membrane of the rough endoplasmic reticulum, not in the ER
