Unformatted text preview: the cytoplasm. The product of an expressed gene can be mRNA, tRNA, rRNA, and polypeptides. A number of different types of RNA exist in prokaryotic and eukaryotic cells. Type of RNA Structure/Location Function mRNA tRNA rRNA The overall structure of RNA is linear (sometimes 3D). An example of 3D RNA is tRNA. You have a sugar phosphate backbone and it has a 5 phosphate group and a 3 hydroxyl group. The nucleotides can only be added to the 3 hydroxyl group. The synthesis of RNA runs from 5 to 3. At the active site, there was a peptide bond being made between amino acids. tRNA is just like mRNA which has a 5 and 3 end. There is an anticodon and runs 3 to 5. There are hydrogen bonds between the bases and which make an antiparallel pattern. (UA and TG like in DNA) The triplet code which is a group of 3 nucleotides to make one amino acid....
