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 ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...
