*A Paradox of Life* 

*B-DNA is needed for maintenance of genetic stability, while it will convert into non-B DNA in replication, repair, transcription or recombination, leading to exposure of bases, single strands, and even introduction of distortions. All these could intrigue gratuitous repair on undamaged DNA using the conventional repair, recombination mechanisms. Repair or not Repair, turns to be a question?*
