Показать описание
Understandings:
Nucleotides are the condensation products of a pentose sugar, phosphoric acid and a nitrogenous base—adenine (A), guanine (G), cytosine (C), thymine (T) or uracil (U).
Polynucleotides form by condensation reactions.
DNA is a double helix of two polynucleotide strands held together by hydrogen bonds.
RNA is usually a single polynucleotide chain that contains uracil in place of thymine, and a sugar ribose in place of deoxyribose.
