DNA is made of two complementary strands running in opposite directions 
(antiparallel). These may be identical in the case of Palendromes, but needn't 
be. So, most DNA is made from two different strands. 

DNA codes for proteins. Does the complementary strand, then, make a different 
set of proteins? Or, in the translation process, does the tRNA treat, for 
example, TGC the same way as it would treat the complementary ACG? 

Thank you for your time in answering this question. Please explain... 
  - if two sets of proteins are made, how the cell regulates this, or,
  - if identical proteins are made, what are the mechanisms which allow this to
