Where do amino acids get attached to tRNA and where is it synthesized?
A pre-tRNA is transcribed from tRNA genes in DNA by RNA polymerase III. … You'll find there's a unique splicing mechanism in tRNA that additionally splices out an anticodon intron which is abesnt in mature tRNA's:
The wikipedia article notes RNA Pol III generally recognizes …

How do cells determine RNA types?
Rather, the gene has the elements, just like it does to select the RNA Pol it needs, to direct the sort of modification the RNA needs to obtain. … The image below depicts two types of RNA transcribed by RNA Pol II and how the processing elements let the modification machinery know how to handle them:

How to isolate host cell RNA (tRNA,mRNA,rRNA) from viral RNA?
Thermo Fisher has a protocol for the separation of host mammalian RNA from prokaryotic RNA, optimized for E. coli vs human, mouse or rat sequences. … Otherwise, Thermo Fisher has additional links to RNA isolation protocol.. most of the viral assays, however, utilize serum, plasma, etc. because host DNA/RNA will elute along with the viral RNA if they're …

H3K36me3 role in RNA polymerase II elongation
Looking at yeast studies, though, it would seem that RNA Pol II is capable of transcribing through heterochromatin anyways so long as specific cofactors are present (Acetylation of H3 K56 Is Required for … RNA Polymerase II Transcript Elongation through Heterochromatin in Yeast) …

What physical force attracts the anti-codon on tRNA to the codon on mRNA during translation?
I wanted to illustrate the process I explained in a comment on aandreev's answer with some images, I just copy/pasted the actual text sections, however.
From comments:
The tRNA is bound to an elonga …
