===Section 6: Biological Unit===
In FirstGlance, in the ''molecule information tab'' click ''Biological Unit''. (It is also in the ''Resources Tab''.)
How many polymer chains (protein, DNA or RNA) are in the biological unit? The asymmetric unit?
How many polymer chains (protein, DNA or RNA) are in the biological unit? The asymmetric unit?
:A. The asymmetric unit is what you see in Proteopedia or FirstGlance, when you use the PDB code.
:B. In a new browser tab, go to [http://watcut.uwaterloo.ca/cgi-bin/makemultimer/ MakeMultimer].
:C. Enter your PDB code. Leave all other options at their defaults. Click Submit.
:D. Pay attention to the tables, especially the "Chain" column (model made by MakeMultimer), vs. the "original" column (original chain names).
:E. Click "View in FirstGlance".


Show side-by-side <font color='e000e0'><b>two snapshots</b></font> comparing the asymmetric unit with the biological unit. The ''Cartoon'' representation in FirstGlance is best for these snapshots. Make sure to label which is which.
