What are the nitrogenous bases in DNA? where and what are they attached to? Best Answer: Nitrogenous bases: A=Adenine T=Thymine G=Guanine C=Cytosine Each base attached to a pentose/five carbon sugar (deoxyribose), and a phosphate group. The phosphate and sugar molecules bind to each other with covalent bond, while the complementary bases bind with hydrogen bond.hey are attached to a five carbon sugar through covalent bonds, and they also form the rungs of the ladder in the double helix through hydrogen bonds. These hydrogen bonds are between two nitrogenous bases.

DNA: Adenine, Guanine, Cytosine, Thymine & Complementary Base Pairing There are four nitrogenous bases found in DNA that are called guanine, adenine, thymine and cytosine. They are abbreviated by the first letter in their name, or G, A, T and C.The bases can be divided into two categories: Thymine and cytosine are called pyrimidines, and adenine and guanine are called purines.he phosphate group and sugar are the same in every nucleotide, but there are four different nitrogenous bases: guanine, adenine, thymine and cytosine. They are often abbreviated by the first letter of each nitrogenous base: G, A, T and C.

Structure of Nucleic Acids Base Pairing in DNA The nitrogen bases form the double-strand of DNA through weak hydrogen bonds. The nitrogen bases, however, have specific shapes and hydrogen bond properties so that guanine and cytosine only bond with each other, while adenine and thymine also bond exclusively. This pairing off of the nitrogen bases is called complementarity.

Nucleotides in DNA Nucleotides in DNA contain four different nitrogenous bases: Thymine, Cytosine, Adenine, or Guanine. Pyrimidines: Cytosine and Thymine each have a single six-member ring. Purines: Guanine and Adenine each have a double ring made up of a five-atom ring attached by one side to a six-atom ring. The order of nucleotides along DNA polymers encode the genetic information carried by DNA. DNA polymers can be tens of millions of nucleotides long.

Structural Biochemistry/Nucleic Acid/Nitrogenous Bases Overview [edit]. A DNA nucleotide is composed of 3 main units: a sugar, a phosphate group, and a nitrogenous base. While the sugar and phosphate group alternate in sequence and form the backbone of the DNA double helix, the nitrogenous bases may differ in every adjoining nucleotide.The four nitrogenous bases present in DNA are adenine (A), guanine (G), cytosine (C) and thymine (T).In RNA, the only differing nitrogenous base is uracil (U) (which replaces thymine in DNA and differs thymine only by the missing methyl group at carbon 5 of the pyrimidine ring).hile the sugar and phosphate group alternate in sequence and form the backbone of the DNA double helix, the nitrogenous bases may differ in every adjoining nucleotide. The four nitrogenous bases present in DNA are adenine (A), guanine (G), cytosine (C) and thymine (T).
