I have a question regarding RNA translation.
Firstly, my book states that Amino-Acids are binded to tRNA through AA-Activation which is possible through ATP->AMP. The AA will then bind to the acceptor stem near 3' end. My question is:
a) Each strand of tRNA can bind only one Amino-Acid?
b) Each strand of tRNA can bind only one type of Amino-Acid?
Then, at a point it is written "The smaller subunit (of ribosomes) has the binding site for mRNA" however, a few paragraphs later, it is stated "The tRNA will bind to the base of the P site on the small subunits". Which one is correct?
Finally, it states the last stage of RNA Initiation as "The large subunit, containing the binding sites for tRNAs joins the complex". What exactly does this mean? Is it the smaller or larger subunit which binds tRNA? What complex is it joining?
Thanks in advance!
