What are the three parts of a DNA nucleotide, and how are they connected to each other? The three parts are a deoxyribose sugar, a phos- phate group, and a nitrogenous base. The phosphate group and the base are connected to different parts of the sugar.Click to see full answer. In this regard, what are the three parts of a DNA nucleotide? Both deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleotides which consist of three parts: Nitrogenous Base. Purines and pyrimidines are the two categories of nitrogenous bases. Pentose Sugar. In DNA, the sugar is 2′-deoxyribose. Phosphate Group. A single phosphate group is PO43-. Secondly, which is the correct identifICation of the parts of the DNA nucleotide? B) A = phosphate, B =ribose, C = uracil D) A = phosphate, B = deoxyribose, C = thymine Page 6 3556 – 1 – Page 4 13) The diagram below represents a portion of a double-stranded DNA molecule. Beside above, what are the three components of a DNA nucleotide quizlet? Terms in this set (17) nucleotide. consists of three parts: a five carbon sugar, a phosphate group, and a nitrogenous base. deoxyribose. the five carbon sugar in a DNA nucleotide. what does the phosphate group consist of? nitrogenous base. purines. pyrimidines. base-pairing rules. complementary base pairs. What makes up a nucleotide?A nucleotide consists of three things: A nitrogenous base, which can be either adenine, guanine, cytosine, or thymine (in the case of RNA, thymine is replaced by uracil). A five-carbon sugar, called deoxyribose because it is lacking an oxygen group on one of its carbons. One or more phosphate groups.
