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 ...

Cytosine can also be isolated from DNA or RNA through enzymatic digestion and chromatographic purification techniques. In DNA, cytosine pairs with guanine through three hydrogen bonds, forming a ...

Traits as diverse as the color of a person's eyes and the scent of a rose are determined by the information contained in DNA. Learn how this information is coded by strings of molecules called ...

Because there are four naturally occurring nitrogenous bases, there are four different types of DNA nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). Within double-stranded DNA ...
