Which compound is formed of a sugar and a nitrogenous base?

Which compound is formed of a sugar and a nitrogenous base?

Deoxyribonucleic acid (DNA)
Deoxyribonucleic acid (DNA) is made up of sugar, a nitrogenous base and a phosphate group (Figure 1.2). The combination of these molecules makes the building blocks for the DNA synthesis.

What nitrogenous bases are found in both DNA and RNA?

The bases adenine, guanine, and cytosine are found in both DNA and RNA; thymine is found only in DNA, and uracil is found only in RNA.

What nitrogenous bases is DNA composed of?

Figure 2: The four nitrogenous bases that compose DNA nucleotides are shown in bright colors: adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue).

How do ribose and deoxyribose sugars differ?

The pentose sugar in DNA is called deoxyribose, and in RNA, the sugar is ribose. The difference between the sugars is the presence of the hydroxyl group on the 2′ carbon of the ribose and its absence on the 2′ carbon of the deoxyribose.

How do ribose and deoxyribose differ?

what is the difference between ribose and deoxyribose? Both are sugars the only difference is deoxyribose is lacking oxygen. If there is an OH bonded to it is ribose and deoxyribose has just a H.

Is nitrogen a base?

Nitrogenous base: A molecule that contains nitrogen and has the chemical properties of a base. The nitrogenous bases in DNA are adenine (A), guanine (G), thymine (T), and cytosine (C). The nitrogenous bases in RNA are the same, with one exception: adenine (A), guanine (G), uracil (U), and cytosine (C).

Which nucleotide component contains nitrogen?

The nitrogenous bases found in nucleotides are classified as pyrimidines or purines. Pyrimidines are heterocyclic amines with two nitrogen atoms in a six-member ring and include uracil, thymine, and cytosine.

What is deoxyribose composed of?

Deoxyribose is an aldopentose, which means a pentose sugar with an aldehyde functional group in position 1. An aldehyde group consists of a carbon atom that is bonded to a hydrogen atom and double-bonded to an oxygen atom (chemical formula O=CH-). Deoxyribose is derived from ribose.

Are ribose and deoxyribose structural isomers?

L-ribose and D-ribose are two optical isomers that can either form a pentagonal or hexagonal ring in aqueous solution. The only difference between the deoxyribose and ribose is the presence or absence of a hydroxyl group at the second carbon of the molecule. Deoxyribose is present in all forms of DNA.

What is the structural difference between ribose sugar and deoxyribose and sugar?

Where are the deoxyribose bases found in DNA?

>deoxyribose sugar in DNA. Attached to the sugar links in the backbone are two kinds of nitrogenous bases: purines and pyrimidines. DNA, organic chemical of complex molecular structure that is found in all prokaryotic and eukaryotic cells and in many viruses.

What kind of sugar is attached to a nitrogenous base?

A nitrogenous base is covalently attached to a pentose sugar, which can be either ribose or deoxyribose. Ribose containing nucleosides are called ribonucleosides or ribosides, while deoxyribose containing nucleosides are called deoxyribonucleosides or deoxyribosides.

What kind of sugar is found in DNA?

You can learn more about this topic in the related articles below. 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.

What makes up the base of a nucleoside?

A nucleoside is made up of a pentose sugar molecule and a nitrogenous base. It does not contain any phosphate group. A nitrogenous base is covalently attached to a pentose sugar, which can be either ribose or deoxyribose.
