For decades, a small group of cutting-edge medical researchers have been studying a biochemical, DNA tagging system, which switches genes on or off. Many have studied it in bacteria and now some have ...

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 ...

Now, researchers at Harvard University have designed a new class of adenine base editors (ABEs) that can efficiently turn A-T into G-C, opening up the majority of pathogenic point mutations for ...

Beijing Zhongke Journal Publising Co. Ltd. This study is led by Professor Lanqin Xia (Institute of Crop Sciences, Chinese Academy of Agricultural Sciences, Beijing, China). The authors isolated a rice ...

Some bacteria-killing viruses spell out their genetic instructions in a different DNA alphabet. More than 40 years ago, scientists in Russia reported that a type of bacteriophage called cyanophage ...
