UCLA Health researchers say study findings uncover Huntington's disease mechanisms and pave new ways to develop treatments.

Other combinations of the atoms form the four bases: thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder. (It takes two bases to form a rung -- one ...

This process is called elongation. Three of the four nitrogenous bases that make up RNA — adenine (A), cytosine (C), and guanine (G) — are also found in DNA. In RNA, however, a base called ...

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 ...

In DNA, cytosine pairs with guanine through three hydrogen bonds, forming a stable base pair. The sequence of these base pairs along the DNA strand encodes genetic information. During DNA replication, ...

DNA is the molecular basis of heredity ... are strict rules about which nucleobase can pair with which. Adenine and guanine are double-ring molecules called purines, but cytosine, thymine and ...

"23andMe's bankruptcy announcement is concerning and I am urging New Yorkers to take action to safeguard their data." ...

“Being able to extend [base editing] to other types is really quite important.” Traditional CRISPR-Cas9 genome editing makes a double-stranded break in DNA in order to introduce insertions or ...
