Purines are double ringed molecules, but I don't think it is accurate to describe them as sugars. Sugars are molecules consisting of carbon, hydrogen, and oxygen, and usually with a ratio of around one carbon to one oxygen to two hydrogens. Purines have multiple nitrogens in their ring structures which I believe disqualifies them from being sugars.
Each nucleotide consists of a sugar in the middle of a phosphate group and a nitrogenous base .There are two classes of bases. Two are purines (double-ringed structures) and two are pyrimidines (single-ringed structures).Very basically, they are made of a nitrogen base, a pentose (5 carbons) sugar and a phosphate group.
RNA and DNA differ in these ways: (1) DNA has deoxyribose sugar, and RNA has ribose sugar. (2) DNA is made up of these four bases: adenine & guanine, cytosine & thymine; RNA is made up of adenine & guanine, cytosine & URACIL, the difference being that in RNA, uracil replaces thymine. (3) DNA is a double stranded molecule, and RNA is a single stranded molecule. (And for an optional 4)RNA can travel in and out of the nucleas of the cell. The DNA is stuck in the nucleas.
Saltine crackers are not considered high in purines. Purines are compounds found in certain foods, particularly meats, seafood, and some legumes, which can contribute to elevated uric acid levels in the body. Saltine crackers are primarily made from flour, water, yeast, and salt, making them low in purines and generally safe for those concerned about purine intake.
RNA does not contain sugar like glucose, but is made up of ribose sugar molecules. A single RNA nucleotide contains one ribose sugar molecule.
No, dextrose is a monosaccharide, specifically a simple sugar known as glucose. Polysaccharides are complex carbohydrates made up of many sugar units linked together.
The sides of the ladder of the double helix are made of groups of hydrogen bonding between the purines and pyrimidines. The backbone is made up of sugar-phosphate.

Nitrogen bases are made up of hydrogen bonds, phosphate, and sugar
Purines. They are one of the two types of nitrogenous bases found in DNA and RNA, and they consist of a double-ring structure. Adenine and guanine are examples of purines.
It is made of two individual sugar monomers bonded together to become a disaccharide.. In other words a double sugar
Disaccharide
Single-stranded DNA is made up of deoxyribose sugar and thymine base, while RNA is made up of ribose sugar and uracil base. DNA is typically double-stranded and carries genetic information, while RNA is usually single-stranded and involved in protein synthesis and other cellular functions.
The DNA is the longest biopolymer discovered. It is made up of two strands that are the polymers of repeating units of deoxyribonucleotides. The deoxyribonucleotides, themselves consist of three moieties: 1. Deoxyribose Sugar: A pentose (5 carbon) Sugar 2. Phosphate: Phosphate group imparts the negative charge to DNA molecule 3. Nitrogenous Bases: These are aromatic compounds that have their basic nature due the presence of Nitrogen. Two types of bases are found in the DNA molecule 1. Pyrimidine: they are single ringed compounds that are derivative of compound called Pyrimidine. There are two types of Pyrimidines in DNA, Cytosine and Thymine. 2. Purines: Purines are derivative of organic compounds called as Purines and have two rings. There are two Purines: Adenine and Guanine) in DNA. The dexoribonucleotides are linked by the reaction of Phosphodiester bond to form one strand of DNA>
The sugar-phosphate backbones are the double helix staircase railings.
altering sugar parts and phospate parts
DNA is a macromolecule made of many nucleotide subunits; these subunits are made of a nitrogen-containing base, a ribose sugar, and a phosphate group. DNA is also associated with many different types of proteins that help keep It maintained and organized within the cell.The bases are either single rings called pyrimidines (Thymine and Cytosine) or double-ringed purines (Adenine and Guanine). The bases (represented as T, C, A or G) are bonded to a deoxyribose sugar, this sugar is also bonded to phosphate groups. The deoxyribose sugars and the phosphate groups alternate to form the backbone of one DNA strand. Two strands are arranged into a double helix, each strand is anti-parallel to the other (they point in opposite directions like lanes in a two way street).DNA is organized and coiled within the cell by histonesand other proteins.*DNA stands for deoxyribonucleic acid
The sides of a double helix are made of repeating units of sugar and phosphate molecules, which make up the backbone of the DNA molecule. These sugar-phosphate backbones are connected by hydrogen bonds between the nitrogenous bases, forming the characteristic twisting structure of the DNA double helix.
