Improve DNA Nodes

[BradyAJohnston]

Issue to track the improved DNA nodes:

• Helix / double helix from curve
• Instancing bases
• Extracting curves from structures
• Joining curves
• Offsetting curves
• Documentation
• cartoon styles for generated DNA / RNA

Hi Brady, can a sequence of DNA be specified as input?

[BradyAJohnston]

Hi @qzchen2022 currently there isn't support for specifying sequence, but this is possible and planned to be added at some point (but it's not a major priority).

The DNA system is undergoing an internal overhaul that I should hopefully release in the next month or two which will enable a lot more functionality like specifying sequence

That sounds fantastic. I have now modified your double-helix DNA geometry node as below. By evaluating the instance index, I can achieve a specified sequence.
