0.1 alpha

Tihamer Toth-Fejel is a 3DS Maxscript written because I needed a model of stylized DNA. Given an arbitrary string of G,T,A, and C, it creates a model of that DNA sequence.

This Alpha 0.1 version has no interface (you need to edit the variable DNAstring below if you want anything different), and there is a bug the last base is not recognized (that is why it's black).

Additional Info: 

For newbies, make sure that this file is in the same directory as StylizedDNABase.max. Then go to MAXScript > Open Script... to open this file. In the MAXScript window do File->Evaluate All (ctrl-E). The first row of DNA should pop up immediately, and then the key will stutter-blink while the MAXScript Listener will get the base letter strings printed to them (this will take a few seconds) until the display catches up.

Tested on 3DS Max 6.0

For atomically precise DNA, I would recommend the powerful (and free) Nanoengineer by Nanorex ( (Full disclosure: I'm on the scientific advisory board of Nanorex, but I also think it's a great tool - otherwise I would have declined.)

I hope you find useful. It is open source and comes with no guarentee.


Here is the experimental data from biology that explains what DNA really is:

1 helical turn = 10 2/3 bases, 3.63 nm
32 bases = three full turns or 33.75 degrees/base
0.3403125 nm/base

There should be crossovers every 1.5 turns (or every odd number of half turns);

'inter-helix gap' depends on crossover spacing,
~1 nm for 1.5-turn spacing and ~1.5 nm for 2.5-turn spacing.

In B-DNA the major grove is wider (1.2 vs 0.6 nm) and deeper (.85 vs .75) than the minor grove.

As you can see, the B-form of DNA is a very floppy molecule. The separation of groves (along axis of DNA) was 2.255 nm (major) and 1.075 nm (minor) (3.33 total);
Or 96.66 degrees (measured in 3DS Max). Color Standard thyamine is yellow; guanine is green, cytosine is red, and adenine is blue

btw does the angles of the

btw does the angles of the connection always have this right angle???

and sometimes thers 3 green in arow, then only one, same with red, and blue?

WOW! just tried it works in

WOW! just tried it works in 2009 64bit as well,
very very nice!!!

can we make recommendations or updates planned???
thanks !
