tRNA

[Emeryx09]

Where is tRNA made, and how? I"m just wondering, because I'm reviewing, and I realized I know how and where mRNA and rRNA are made..

[sorin]

in the nucleus (nucleoplasma, not nucleoli), however in contrast to mRNA not by Pol II but by Pol III (like the 5 S rRNA). There are several copies of the different tRNA genes throughout the genome, however i don't know the exact number now. hope it helped you...

if i remember correctly
t-RNA can also be made in the mitochondria.
but yes most of it comes from the nucleolus as the above post said.

as to how is it made i have no clue. though it must use the DNA as a template

hi i was just wondering whats the difference between RNA mRNA and tRNA arn't they all the same thing

They are all made of the same thing (RNA) but have different functions. So they are the same thing just as proteins are the sane thing. They are all polymers of amino acids, but with lots of different functions.

Just to make it crystal clear, the proteins are polymers of amino acids, the RNA is polymer of other monomers
As canalon said, they have different function, but also different size and shape
