What is the role of tRNA in protein synthesis?

Can anyone briefly describe the role of mRNA, tRNA and rRNA in protein synthesis?

• Answer:

  The following is probably the simplest terms this can be explained in: mRNA (messenger RNA) is the result of transcription--when the RNA polymerase reads DNA, it reduces an mRNA, which carries a copy of the message the DNA carries. This is the body's way of telling the ribosomes within the cell what the DNA says. tRNA (transfer RNA) is the RNA that is picked up by ribosomes during translation. tRNAs connect to amino acids based on the codon they carry. Ribosomes read mRNA strands and pick up tRNAs from the cytoplasm, adding different types of tRNAs based on what the codons on the mRNA say. rRNAs are used by ribosomes to read mRNA and tRNA for use in translation.
