UNANSWERABLE
who is robert dirks? An American chemist known for his theoretical and experimental work in DNA nanotechnology. what is the full form of dna? Deoxyribonucleic acid what are the applications of the last technology you mentioned? X-ray crystallography, nuclear magnetic resonance spectroscopy of proteins what are its different types of designs? Structural design, Sequence design what can you tell me about the first type? Representation by a specific arrangement of nucleic acid strands. and the second type? Nucleic acid design is the process of assigning a specific nucleic acid base sequence to each of a structure's constituent strands so that they will associate into a desired conformation.

DNA nanotechnology [SEP] Sequence design
After any of the above approaches are used to design the secondary structure of a target complex, an actual sequence of nucleotides that will form into the desired structure must be devised. Nucleic acid design is the process of assigning a specific nucleic acid base sequence to each of a structure's constituent strands so that they will associate into a desired conformation. Most methods have the goal of designing sequences so that the target structure has the lowest energy, and is thus the most thermodynamically favorable, while incorrectly assembled structures have higher energies and are thus disfavored. This is done either through simple, faster heuristic methods such as sequence symmetry minimization, or by using a full nearest-neighbor thermodynamic model, which is more accurate but slower and more computationally intensive.
