How do mRNA, tRNA and rRNA work together in translation to build protein?

Question

mRNA is the manual, tRNA carries amino acids, rRNA is the factory

The mRNA (messenger RNA) carries the info regarding what protein is to be made. Which amino acid is supposed to be where is written in here.

The tRNA (transport RNA) carries the amino acid to the rRNA.

The rRNA (ribosomal RNA) makes up the ribosome. The ribosome builds the protein according to the instructions written in the mRNA with the amino acids ferried in by the tRNA.

Three roles of RNA in protein synthesis:

undefined mRNA carries the genetic code from DNA to the ribosome. tRNA brings amino acids to the ribosome based on the mRNA sequence, matching the codons on mRNA with anticodons on tRNA. rRNA is a structural component of the ribosome, facilitating the binding of mRNA and tRNA and catalyzing the formation of peptide bonds between amino acids, thus assembling the protein according to the mRNA sequence.
