Abstract
Research in nucleic acids has made major advances in the past decade in multiple fields of science and technology. Here we discuss some of the most important findings in DNA and RNA research in the fields of biology, chemistry, biotechnology, synthetic biology, nanostructures and optical materials, with emphasis on how chemistry has impacted, and is impacted by, these developments. Major challenges ahead include the development of new chemical strategies that allow synthetically modified nucleic acids to enter into, and function in, living systems.
