The
idea
|
|
Cronenberg,
Germany, April 2004
When I saw this old sewing machine, by my wife's cousin Ortrun, I immediately
knew what to do with it. It should saw together the nucleic acids which
compose the bases connecting the DNA spirals.

June 25
I tried various ways to build the DNA spirals.
Finally I decided to use some tiny (6mm diameter) cupper pipes, form it
in spiral around a 20 cm diameter duct, and pass ping-pong balls through
it. I bought 500 of them.
Additional problems showed up during this trials, like how to build the
nucleic acids bases crossing from one spiral to the other. Also how to
make the whole assembly rigid and stable.
Solutions are on the way.

Sept 15
I found in an antique shop in Siena a complete sawing machine table with
the pedal, the wheel and a nicer machine. I bought it.
Oct1, 2004
During the last 2 months I worked occasionally on this project.
This is were it stands today.
The sugars and phosphates make the white and violet spirals. The nucleic
acids A &T are red & yellow, and C & G are blue & green.

Oct 17
Made 4 glass jars filled with the 4 nucleic acids as ping-pong balls,
yellow for Adenine, red for Thymine, blue for Cytosine and green for Guanine.
Made tags for these names and added the chemical formula of each. The
jars rest upside down on a tablet with holes which let a small chain of
balls come down out to be sewed together by the machine.
