What are the 5 carbon sugar in DNA?

ribose, also called D-ribose, five-carbon sugar found in RNA (ribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the RNA polymer and binds to nitrogenous bases.

Is the five carbon sugar found in DNA and RNA?

Five-Carbon Sugar

The pentose sugar in DNA is deoxyribose and in RNA it is ribose.

What are the sugars found in DNA?

deoxyribose
DNA consists of a pair of chains of a sugar-phosphate backbone linked by pyrimidine and purine bases to form adouble helix (Fig. 96.1). The sugar in DNA is deoxyribose. The pyrimidines are cytosine (C) and thymine (T); the purines are guanine (G) and adenine (A).

What are the 6 carbon sugars?

The common six-carbon sugars (hexoses) are D-glucose, D-fructose, D-galactose, and D-mannose. They all are aldohexoses, except D-fructose, which is a ketohexose.

Is glucose a 5 carbon sugar?

Based on the number of carbon atoms it contains, a monosaccharide can be called a triose (C3H6O3), a tetrose (C4H8O4), and so on. Glucose is a hexose, with six carbon atoms (Fig.

What are 2 purines in DNA?

Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)). These nitrogenous bases are attached to C1′ of deoxyribose through a glycosidic bond.

What are the sugar in DNA and RNA?

There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

What are the 4 DNA bases?

There are four nucleotides, or bases, in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). These bases form specific pairs (A with T, and G with C).

What is the name of the sugar in the DNA backbone?

deoxyribose
DNA consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

What are examples of purines?

Examples of purines are adenine and guanine. Purines are also found in meat and meat products. They are broken down by the body to form uric acid, which is passed in the urine.

Is deoxyribose A purine or pyrimidine?

Table 17.1. 1: Composition of Nucleotides in DNA and RNA

How many deoxyribose sugars are in this strand of DNA?

five
DNA is made up of five carbon sugar (deoxyribose), one phosphate group and four bases.

What is at the 5 end of DNA?

The 5′-end (pronounced “five prime end”) designates the end of the DNA or RNA strand that has the fifth carbon in the sugar-ring of the deoxyribose or ribose at its terminus.

Is deoxyribose A 5 carbon sugar?

deoxyribose, also called d-2-deoxyribose, five-carbon sugar component of DNA (q.v.; deoxyribonucleic acid), where it alternates with phosphate groups to form the “backbone” of the DNA polymer and binds to nitrogenous bases.

Is DNA A six carbon sugar?

DNA is a polymer. The monomer units of DNA are nucleotides, and the polymer is known as a “polynucleotide.” Each nucleotide consists of a 5-carbon sugar (deoxyribose), a nitrogen containing base attached to the sugar, and a phosphate group.

What group is attached to the 5 carbon?

phosphate group
The phosphate group attached to the 5′ carbon of the sugar on one nucleotide forms an ester bond with the free hydroxyl on the 3′ carbon of the next nucleotide.
