what are the sugars of dna?
145896
Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).

Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Nucleotides each have three parts: phosphate, sugar molecule, and one of four bases. The bases include: A, (adenine), g (guanine), t (thymine), c (cytosine). The phosphate and sugar molecule bonds form the backbone or hand rail of the DNA (staircase), but the genetic key is in the steps (of the stairs): the bases.

Now let's consider the structure of the two types of nucleic acids, deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). The building blocks of DNA are nucleotides, which are made up of three parts: a deoxyribose (5-carbon sugar), a phosphate group, and a nitrogenous base (Figure 9.3).

The sugar-phosphate backbone forms the structural framework of nucleic acids, including DNA and RNA. ... DNA and RNA are composed of nucleotides that are linked to one another in a chain by chemical bonds, called ester bonds, between the sugar base of one nucleotide and the phosphate group of the adjacent nucleotide.

The Building Blocks of DNA DNA has three types of chemical component: phosphate, a sugar called deoxyribose, and four nitrogenous bases—adenine, guanine, cytosine, and thymine. Two of the bases, adenine and guanine, have a double-ring structure characteristic of a type of chemical called a purine.

What is DNA made of? DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.

Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy").

DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the nitrogenous base thymine, while RNA contains the nitrogenous base uracil. The diagram below shows the structure of a DNA nucleotide. The sugar is deoxyribose, and adenine is one of four possible nitrogenous bases.

Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T).

DNA and RNA are made up of three component: the sugar, the nitrogeneous base, and the phosphate group.

Deoxyribose consists of five carbon atoms that form a pentagonal shape. As you can tell by its name, deoxyribose is a particular type of sugar known as a pentose monosaccharide, which contains five carbon atoms. Ribose, which is contained in the name, is also considered a pentose monosaccharide.

Sugar. Both DNA and RNA are built with a sugar backbone, but whereas the sugar in DNA is called deoxyribose (left in image), the sugar in RNA is called simply ribose (right in image).
1171682
The five-carbon sugar in DNA is called deoxyribose, while in RNA, the sugar is ribose.
1340491
RNA and DNA molecules have ribose and deoxyribose sugar respectively. Both are chiral, their chirality is due to D -ribose or deoxyribose sugar components.

Ribose, found in RNA, is a "normal" sugar, with one oxygen atom attached to each carbon atom. Deoxyribose, found in DNA, is a modified sugar, lacking one oxygen atom (hence the name "deoxy"). ... Notice the difference between ribose and deoxyribose in the figure above.
