This image illustrates the chemical structures of the five main nucleobases found in DNA and RNA. The pyrimidines, thymine (DNA), uracil (RNA), and cytosine are shown on top while the purines, adenine ...
Molecular models are a tried-and-tested tool for teaching chemistry to students of all ages. By enabling users to visualize the three-dimensional structure of a molecule and how its atoms are arranged ...
Chemists in the United States have made an artificial DNA-like molecule that can change its sequence to bind to a DNA template without the help of enzymes. The findings could shed light on how ...
This image depicts the chemical structure of cytosine. It shows a hexagonal ring with nitrogen atoms at positions 1 and 3, and a primary amine group attached to carbon 4. The two remaining positions ...
In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3D structures, including miniature biosensors and drug-delivery containers.
Proteins bind to one another through a complex mix of chemical interactions. What if some proteins bind due to their shapes, a much simpler process? To answer this question, researchers used Summit, ...
Scientists at TU Delft and the Max Planck Institute have made a new class of structurally adaptable ‘mechanical’ pores made from DNA that can transport molecules through cell membranes. These ...
Prime It, created by the University of Glasgow’s School of Life Sciences, is probably the most fun that you can have with PCR. The app is mostly based around a great game that challenges the user to ...
DNA shows promise as a material for data storage because it resists degradation and can pack a lot of information into a small volume. But reading the stored data typically requires sequencing the DNA ...
