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 ...

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 ...

adenine (A), thymine (T), guanine (G), and cytosine (C). Within double-stranded DNA, the nitrogenous bases on one strand pair with complementary bases along the other strand; in particular ...

adenine, guanine, cytosine, thymine, and uracil. (Where DNA uses thymine, RNA uses uracil.) Two nucleotides together form a ...

which can be an adenine (A), thymine (T), guanine (G) or cytosine (C). Bases are complementary. This means they always pair in the same way: A with T, T with A, C with G and G with C.
