Question

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

Answer 1

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

Explanation:

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:
