:Thanks.
Please let me know if you find anything out about the structure of 
thier DNA. I just learnt about A B and Z structures of DNA. The 
intresting one is the Z structure because it is very hard to find in 
large quantities in living things.  The reason is that it goes against 
the hydrologicall characteristics of the molecule. It turns out that is 
will occur in very saly solutions. I was hinking where on earth is it 
very salty (I mean VERY salty ) and I thought that at the vents at the 
bottom of the ocean water would evaporate and so the salt concentration 
would go up.  WHat do you all think?
