With the arrival of a new class of single-nucleotide editors, researchers can target the most common type of pathogenic SNP in humans. Now, researchers at Harvard University have designed a new class ...

DNA is composed of building blocks called nucleotides, each of which carries one of the following bases: adenine, guanine, thymine or cytosine. These bases are the individual letters that make up ...

The cause is related to expansion of repeating DNA units, in which specific strings of genetic code-in this case, a series of cytosine-adenine-guanine nucleotides, or CAG, on one strand of the DNA ...
