This review covers studies which exploit triazole-modified nucleic acids in the range of chemistry and biology to medicine. The 1,2,3-triazole unit, which is obtained via click chemistry approach, shows valuable and unique properties. For example, it does not occur in nature, constitutes an additional pharmacophore with attractive properties being resistant to hydrolysis and other reactions at physiological pH, exhibits biological activity (i.e., antibacterial, antitumor, and antiviral), and can be considered as a rigid mimetic of amide linkage. Herein, it is presented a whole area of useful artificial compounds, from the clickable monomers and dimers to modified oligonucleotides, in the field of nucleic acids sciences. Such modifications of internucleotide linkages are designed to increase the hybridization binding affinity toward native DNA or RNA, to enhance resistance to nucleases, and to improve ability to penetrate cell membranes. The insertion of an artificial backbone is used for understanding effects of chemically modified oligonucleotides, and their potential usefulness in therapeutic applications. We describe the state-of-the-art knowledge on their implications for synthetic genes and other large modified DNA and RNA constructs including non-coding RNAs.

Abstract Clustered regularly interspaced short palindromic repeats (CRISPR) and accompanying CRISPR-associated (Cas) proteins provide RNA-guided adaptive immunity for prokaryotes to defend themselves against viruses. The CRISPR-Cas systems have attracted much attention in recent years for their power in aiding the development of genome editing tools. Based on the composition of the CRISPR RNA-effector complex, the CRISPR-Cas systems can be divided into two classes and six types. In this review, we summarize recent advances in the structural biology of the CRISPR-Cas-mediated genome editing tools, which helps us to understand the mechanism of how the guide RNAs assemble with diverse Cas proteins to cleave target nucleic acids.
