Once our dna sends out a signal to make proteins, it's the job of the to receive this genetic message from the dna and to make and transport the required proteins for use inside and outside the cell.

Answer

          The blank is filled with RNA

Explanation

          As we know that there are three types of RNA responsible for protein synthesis.

1. mRNA

             It is that type of RNA which is the exact copy of DNA template and contain the code copied from DNA for required protein.

2. rRNA

            This RNA play a key role in the formation of ribosomes, a smaller organelle inside cell responsible for holding mRNA during protein synthesis.

3. tRNA

           This RNA transport amino acids to the strand of mRNA and help in translation.
