4. Pick out the correct steps to find out the number of Carbon atoms in Carbon
dioxide using the Ras Mol software.
Open pdb file of the molecule RasMol from import in File menu,
Select structure from colors menu and type 'Select Carbon' then press enter key.
Select Carbon from scroll bar in view menu
Open the file pdb of the molecule in file menu of Rasmol software
Activate command prompt in View menu then type 'select Carbon' in Terminal window
and press enter key

Explanation:
RasMol is a widely used molecular graphics program for visualizing three-dimensional structures of proteins, nucleic acids and small molecules. It is easy to use, runs on many platforms, requires meager computational resources, is extremely powerful, and is free! The program can be used for analysis, display, teaching and generation of publication quality images. RasMol runs on PC, MACs, SGIs etc. The program reads molecular coordinates such as the x,y,z coordinates in a PDB file, Tripos Associates' Alchemy and Sybyl Mol2 formats, Molecular Design Limited's (MDL) Mol file format, Minnesota Supercomputer Center's (MSC) XYZ (XMol) format and CHARMm. Rasmol interactively displays molecules in many representations and colors. Molecules can be shown as wireframe bonds, cylinder 'Dreiding' stick bonds, alpha-carbon trace, space-filling (CPK) spheres, macromolecular ribbons (either smooth shaded solid ribbons or parallel strands), hydrogen bonding and dot surface representations. Various parts of a molecule can be independently represented and colored. A molecule can be rotated, translated, zoomed and z-clipped (slabbed) using either the mouse, the scroll bars, or the command line. Images may be written out in a variety of formats including either raster or vector PostScript, GIF, PPM, BMP, PICT, Sun rasterfile or as a MolScript input script or a Kinemage. Rasmol has no capability for docking and model building.
Here is a list of mouse commands that you can use for manipulating structures. Just click and drag across the main window to rotate, translate, and zoom. X and Y are in the plane of your screen. Z is perpendicular to the screen.
