RasMol
RasMol is an important scientific tool for visualization of molecules created by Roger Sayle in 1992. It is a molecular graphics program intended for the visualization of macromolecules like proteins, nucleic acids and small molecules and to prepare publication-quality images. Rasmol is a free software which can be downloaded from its website. It runs on Windows or Macintosh/PC computers. A free Protein Data Bank file (.pdb file) can be downloaded for each molecule you wish to view. It is very easy to rotate a protein or DNA molecule and show its three-dimensional structure. The detailed using instructions will be explained step- by- step in the following.
