Types of RNA In the synthesis of protein, three types of RNA function. The first type is called  ribosomal RNA (rRNA) . This form of RNA is used to manufacture ribosomes.  Ribosomes  are ultramicroscopic particles of rRNA and protein. They are the places  (the chemical “workbenches”) where amino acids are linked to one another to  synthesize proteins. Ribosomes may exist along the membranes of the endoplasmic  reticulum or in the cytoplasm of the cell.  A second important type of RNA is  transfer RNA (tRNA) . Transfer RNA exists in the cell  cytoplasm and carries amino acids to the ribosomes for protein synthesis. When protein  synthesis is taking place, enzymes link tRNA molecules to amino acids in a highly

In the nucleus, messenger RNA receives the genetic code in the DNA and carries the code into the cytoplasm where protein synthesis takes place. Messenger RNA is synthesized in the nucleus at the DNA molecules. During the synthesis, the genetic information is transferred from the DNA molecule to the mRNA molecule. In this way, a genetic code can be used to synthesize a protein in a distant location. RNA polymerase , an enzyme, accomplishes mRNA, tRNA, and rRNA synthesis....
