[MeltSim] Question about strand concentration

[Marx, Kenneth]

Boy, I thought Paul Doty was old when he was at the Albany meeting ~6 yrs ago. He really does span 2-3 generations of DNA physical property researchers. Now I don't feel so old- although that won't last for long.
 
All the Best, Ken

Hi Ken,
It was good to hear from you. Yes, things are going well, although at 
a snail's pace as you can imagine.
I began research at Harvard in Paul Doty's laboratory with Jacques 
Fresco in 1958, and one of my first experiments was to prepare 
oligonucleotides and study their interaction with polynucleotides. 
The way oligo-poly- complements interacted established the importance 
of stacking forces. (I think I might have written a simple function 
somewhere in my book to account for concentration). Such work was 
carried out so long ago. I will be attending Paul Doty's 90th 
birthday in June, can you imagine?
regards, dick
