Deoxyguanosine is a nucleotide base which plays a crucial role in the structure and function of DNA. There are a few synonyms used for deoxyguanosine, including desoxyguanosine, 2'-deoxyguanosine, and dG. These synonyms are often used interchangeably in scientific literature, and they all refer to the same molecule. Deoxyguanosine is composed of a nitrogenous base, guanine, attached to a deoxyribose sugar molecule, which is then phosphorylated to form a nucleotide. This nucleotide base forms a pair with cytosine in the DNA double helix, and mutations in deoxyguanosine can lead to consequential changes in genetic information. Understanding these synonyms for deoxyguanosine is important for scientists researching DNA structure and function.
