Homework 2008 (due in one week - January 21th)

1) Download the protein PDB file: 1BGY

2) write a interactive I/O perl script to do:
   Extracts: 
   a) the NAME of the protein,
   b) the SOURCE of the protein,
   c) the RESOLUTION of the structure
   d) and for all CHAINS: the following info
       1) The CHAIN number,
       2) Residue name and the sequence number
       3) The number of atoms for each residue
   Prints out all above information either to a file or to the screen.

Note that you can "capture" a screen print with:
"perl your_script.pl > output.file"



The output should look something like:

NAME     CYTOCHROME BC1 COMPLEX FROM BOVINE

SOURCE   MOL_ID: 1;                                                           
SOURCE   2 ORGANISM_SCIENTIFIC: BOS TAURUS;                                    
SOURCE   3 ORGANISM_COMMON: BOVINE;                                            
SOURCE   4 ORGAN: HEART;                                                       
SOURCE   5 TISSUE: HEART MUSCLE;
