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 ...

By treating DNA as a language, Brian Hie’s “ChatGPT for genomes” could pick up patterns that humans can’t see, accelerating ...

Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

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 ...

The thymine-adenine (T-A) base pair is held together by fewer hydrogen bonds compared to the guanine-cytosine (G-C) base pair, which has three hydrogen bonds. The complementary base pairing in DNA ...

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 ...

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 ...

People genetically susceptible to Huntington's disease often see their movement, mood, and cognition decline slowly over time. The cause is related to expansion of repeating DNA units, in which ...
