[Current Knowledge of Base Editing and Prime Editing]

Modern genetic engineering technologies, such as base editing and prime editing (PE), have proven to provide the efficient and reliable genome editing tools that obviate the need for donor templates and double-strand breaks (DSBs) introduced in DNA. Relatively new, they quickly gained recognition for their accuracy, simplicity, and multiplexing capabilities. The review summarizes the new literature on the technologies and considers their architecture, methods to create editors, specificity, efficiency, and versatility. Advantages and disadvantages of the editors are discussed along with their prospective use in basic and applied research. The review may be useful for planning genome editing studies and analyzing their results to solve various problems of fundamental biology, biotechnology, medicine, and agriculture.
