Review Questions

• How do DNA origami templates utilize the principles of base pairing to create specific shapes at the nanoscale?
  • DNA origami templates take advantage of the natural base pairing rules where adenine pairs with thymine and cytosine pairs with guanine. By strategically designing a long single strand of DNA to fold back on itself and hybridize with complementary sequences, researchers can create intricate 2D and 3D shapes. This precise control over molecular interactions allows for the formation of stable structures that can be tailored for various applications.
• Discuss how DNA origami templates can be used as scaffolds for assembling other molecular components and the significance of this capability in nanotechnology.
  • DNA origami templates can act as scaffolds by providing a defined structure upon which other molecules, like proteins or nanoparticles, can be organized. This capability is significant because it allows scientists to design complex nanoscale assemblies with precise positioning and orientation, enhancing their functionality. For instance, such assemblies can improve the efficacy of drug delivery systems or contribute to novel biosensing devices that require high specificity.
• Evaluate the implications of using DNA origami templates in targeted drug delivery systems and how they could change medical treatments.
  • The use of DNA origami templates in targeted drug delivery systems presents significant implications for medical treatments by enabling localized release of therapeutics directly at diseased sites. By engineering these structures to respond to specific biological signals or conditions, such as pH or enzyme presence, they can ensure that drugs are activated only in the intended location. This targeted approach not only enhances the effectiveness of treatments but also minimizes side effects, revolutionizing how therapies are administered in the future.
