What is functional RNA?
My CGP textbook says RNA used in protein synthesis, my official AQA textbook doesn't give a definition and I've looked online and it says non-coding RNA.

It's non-coding RNA so things like ribosomal RNA or tRNA

As KyotheThe Arcane says, correctly, RNA other than mRNA = messenger RNA.

You probably know that:-
rRNA = ribosomal RNA is present in ribosomes together with about 80 different proteins that make up the 50S and 30S subunits of the ribosome ("S" stands for Svedberg unit, which is a function/calculation of the mass, shape, density, etc. manifested as the rate of sedimentation during centrifugation) in prokaryotes (60S and 40S in eukaryotes).

tRNA = transfer RNA, which binds to a specific amino acid by its variable end (anticodon: complimentary base pair sequence to the codon for the same amino acid on mRNA) to form amoniacyl-tRNA, which carries the amino acid to the A site on the ribosome to attach to the previous amino acid in the sequence on the nascent (=in the process of synthesis) peptide chain in due course.

If you need further guidance on protein synthesis, go to my at-d PowerPoint file.
