Ribonucleic Acid (RNA)
• Composed of nucleotides• String of nucleotides forms
single stranded helix• Helix bends and twists to
create 3D structure

RNA Structure• Structure is important to function• Many functions
o Protein synthesiso Genetic material (in some viruses)

Goals and Methods• Describe the geometry and topology of RNA
• Modify previously used methods for DNA for use with RNA
