All of the following are true about the structure of deoxyribonucleic acid except __________. View Available Hint(s) All of the following are true about the structure of deoxyribonucleic acid except __________. deoxyribonucleotides consist of a nitrogenous base and a pentose sugar with the nitrogenous bases covalently bonded to make the primary structure complementary base pairing between the nitrogenous bases from two strands of nucleotides forms the secondary structure of DNA phosphodiester bonds connect deoxyribonucleotides in the primary structure of DNA a single nucleotide has a phosphate group, pentose sugar, and nitrogenous base. The primary structure of DNA consists of nitrogenous bases sticking out from the backbone nucleotides consist of a phosphate group, pentose sugar, and nitrogenous base. The primary structure of DNA has a sugar-phosphate backbone.

Answer:

deoxyribonucleotides consist of a nitrogenous base and a pentose sugar with the nitrogenous bases covalently bonded to make the primary structure

Explanation:

A deoxyribonucleotide is a nucleotide that consists of a nitrogenous base (i.e., purine or pyrimidine) that binds to deoxyribose (i.e., a pentose sugar-containing five carbon atoms), and one phosphate group attached to the nitrogenous base. In the DNA, there are four types of nitrogenous bases: two purines (Adenine and Guanine), and two pyrimidines (Cytosine and Thymine). All these bases are attached to 1' carbon (C1') of deoxyribose by a glycosidic bond. A nucleoside is a nitrogenous base linked to ribose (in RNA) or deoxyribose (in DNA).

The untrue statement about the structure of DNA is deoxyribonucleotide consist of a nitrogenous base and a pentose sugar with the nitrogenous bases covalently bonded to make the primary structure.

DEOXYRIBONUCLEIC ACID:

  • Deoxyribonucleic acid is a type of nucleic acid that stores genetic information in living cells.

  • DNA is a polymer made up of monomers called nucleotides. The nucleotides are the basic unit of the DNA molecule.

  • A nucleotide comprises of three components namely: nitrogenous base, pentose sugar and phosphate groups.

  • A covalent bond called phosphodiester bond connect nucleotides in the primary structure of DNA.

  • Therefore, the untrue statement about the structure of DNA is deoxyribonucleotide consist of a nitrogenous base and a pentose sugar with the nitrogenous bases covalently bonded to make the primary structure.
