Thank you Elaine for the help.

Dear Sanjeev Sariya,
There are 2 copies of the protein in this structure, plus glycosylations, water, ions, etc. This is just the contents of the PDB file. If you look at the page at the RCSB PDB for this structure:
… it says there are 2 chains of rhodopsin, A and B. Any display program will show both chains when you open the PDB file, but you can hide or delete parts of the structure (such as one chain) as you wish. For example, in Chimera you could use menu:
Select… Chain… B
Actions… Atoms/Bonds… delete
to delete chain B. In general, any molecular display programs will also allow showing/hiding, coloring, changing display style, etc. of specific residues and atoms within each chain. For example, to color only residue 113 in chain A:
color red :113.A
There is a manual page on command-line specification:
If you are a Chimera beginner, I recomend the "getting started" tutorial on our website:
There are also several tutorials in the User's Guide, ranging from beginner to more advanced (see Chimera menu: Help… Tutorials).
I hope this helps,
