Oh Come on!! 
Give the guy a break!
I'm sure he is wondering if Silicon could take the place of carbon and
form a similar structure as that of DNA

	Structure involving two antiparallel, hydrogen-bonded polynucleotide
chains wound into a right-handed helical configuration.

Perhaps, phosphodiester bonds could link rings of silicon, but what
about the h-bonding necessary between the amino acids? 
Anyone know?  Is is possible to get silicon to form a structure similar
to a nucleotide?
