Re: Is DNA living or non-living thing?? get the answer here

... this mass-energy dualism also the quantity of energy in the universe is constant. Since the last big-bang all mass formats undergo the same cyclic sequence like the universe itself i.e. birth – evolution – survival – replication. In order to survive and to repeat this sequence every mass format ...

Because later in the lab, we did a whole bunch of sequence alignments with our gene (of both strands) and BLASTed it. But...I am just not really sure if I've done the PCR reactions correctly. Any help ...
