Answers:the three parts are: (1) a nitrogenous base known as purine (adenine (A) and guanine (G)) or pyrimidine (cytosine (C) and thymine (T)); (2) a sugar, deoxyribose; and (3) a phosphate group for base-pairing, adine and guanine always come together as a pair and cytosine and thymine come together AG and CT not sure about who they got hints from to dicover double-helical structure.
Answers:A 'DNA nucleotide' is made up of three molecules bonded together. A phosphate molecule, a sugar called deoxyribose, and a nitrogen base. The nitrogen base could be adenine, thymine, guanine or cytosine. The nitrogen base is what connects to its pair in the broken DNA chain during replication with a hydrogen bond.
Answers:A nucleotide consists of a Phosphate group, a Pentose Sugar and a Nitrogenous base, the Phosphate is bonded to the sugar and the base is also connected to the sugar.
