(Image: Public Domain) Guanine has the chemical formula C₅H₅N₅O and a molecular weight of 151.13 g/mol. It is a polar molecule due to the presence of the carbonyl (C=O) and amino (NH₂) groups. The ...

Adenine and guanine are double-ring molecules called ... can only bond with double rings on the other. This keeps the DNA ...

Whether it is a microbe, a rose, or a dolphin, any form of life gets its building and operating instructions from the molecule of life ... (T), cytosine (C), and guanine (G).

DNA is a linear molecule composed of four types of smaller chemical molecules called nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). The order of these bases is called ...

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 for each side of the ladder.) A sugar molecule, a ...

It is a polymeric molecule composed of nucleotides, each containing a ribose sugar, a phosphate group, and one of four nitrogenous bases: adenine (A), uracil (U), guanine (G), or cytosine (C). RNA is ...
