Morphological variation in folded duplex DNA chains.

I have monitored the packaging process of giant DNA chains with various condensing agents, such as polyamines, polyethylene glycol having pendant aminogroups and a lipospermine, under fluorescence microscopy. The detail morphological structure of the compacted DNA has been observed using electron microscopy. It has become clear that the difference in the folding process results in a large polymorphism of compacted DNA. I discuss the biological importance of controlling the compacted structure.
