Nucleic Acid Structures

DNA dinucleotide steps
Simple DNA Duplexes
- B Form - "normal" DNA
- A Form -> compared with B
- Z Form -> compared with B
- A, B, Z DNA Comparison
- A, B Pucker Comparison
- PNA (Peptide-Nucleic Acid) -> compared with B
- Quadruplex
- T7 RNA Polymerase Promoter
RNA "enzymes" and other molecules
- Hammerhead Ribozyme and an (intermediate)
- Group I Ribozyme
- Ribosome!
- Pseudoknot
Protein/Nucleic Acid Complexes
- Engrailed homeodomain protein (see also a static picture, another, and another)
- IHF protein
Water!
