Are the tRNAs molecules floating in the nucleoplasm, where transcription of DNA sequence occurs?

Ok if we want to get really specific, don't know if you want to or not, tRNA is found for a very small amount of time in the nucleoplasm (which is only present in eukaryotic cells) when it is initially being made but soon after being being "cut" into its correct sections, it is exported outside the nucleus. All of this happens right in the cytoplasm in prokaryotes since they don't have any nucleus. In the cytoplasm it is folded into shape and thus is able to function. All translation happens in the cytoplasm and as tRNA is an important piece in this process, it is found functioning in the cytoplasm.

the trna molecule helps the process of translation.
translation or the synthesis of protein take place in the cytoplasm at the ribosomal site.
the trna molecules are transcibed by the enzymeRNA POLYMERASE and is localized to the nucleolar-nucleoplasm interface.
so at the time of translation the trna molecule travels all the way down in the cytoplasm at the ribosomes to complete translation process.

In prokaryotes there are no organelles so they are just in the cytoplasm.
In Eukaryotes you have tRNAs in the cytoplasm. These take part in the translation of most mRNAs. However mitochondria and chloroplasts also have their own DNA, transcription and translation machinery. So you have tRNAs also in these organelles. However these are confined in the organelles and participate only in the production of some proteins specific for these organelles.

I'd expect to find tRNA in the cytoplasm, or in the rough endoplasmic reticulum, near the ribosomes where translation of the mRNA into polypeptide sequences is occurring.

In the cytoplasm of the cell as it is responsible for tranfering amino acids from the nucleus to the ribosomes where proteins are made

I believe it is mostly found in the cytoplasm of the cell as it is responsible for tranfering amino acids from the nucleus to the ribosomes where proteins are then made.

In eukaryotic cells, they are produce in the nucleus by transcription, but they function in the cytoplasm of the cell where they are involved in translation of mRNA by ribosomes.

hey, actually it isn't a scam. I am very serious. I have cash in my paypal, but it takes 3-4 days for bank draft. i wanted to play last night cause i am impatient. What's your username? We can play heads up anytime on Stars. BA22

hcbiochem has answered this one correctly. Ketchup is completely ignorant because there are no nuclei in prokaryotes, and there are no prokaryotic "animals." Nice try. Thanks for the laugh, Ketchup.

they r present in genes in nucleus
of prokaryotic animals
