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 ...

In DNA, cytosine pairs with guanine through three hydrogen bonds, forming a stable base pair ... For example, a point mutation where cytosine is replaced by thymine (C-to-T transition) is a common ...

but cytosine, thymine and uracil are all pyrimidines: single rings. To maintain its orderly structure, single rings on one ...

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 ...

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 ...
