In vivo base editing enables precise, single-nucleotide changes to DNA without double-strand breaks. A recent application in ...

The next step will be testing whether these synthetic bases also work with the main DNA copying enzyme, which would allow them to be used much more widely. After that, ...

Scientists successfully achieve A to G base conversion, ... Targeted A-to-G base editing in human mitochondrial DNA with programmable deaminases. Cell, 2022; DOI: 10.1016/j.cell.2022.03.039; ...

Our genomic DNA is comprised of four bases—cytosine (C), thymine (T), guanine (G) and adenosine (A). These bases join together into approximately 3 billion different base pairs, arranged in a ...

Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one ...

Image Credit: Andy Leppard DNA is a series of base pairs, or nucleotides: adenine, thymine, guanine and cytosine, called A-T-G-C for short. When CRISPR converts a C:G base pair to a T:A pair ...

His cytidine base editor (also called a cytosine base editor), first described in 2016, uses an enzyme called cytidine deaminase to ultimately convert a C into a T in DNA. Liu’s adenine base ...
