Is deoxyribose a nucleic acid?

Is deoxyribose a nucleic acid?

Deoxyribose nucleic acid (DNA) was first discovered in 1869 by the Swiss scientist, Friedrich Miescher. Nucleic acids are biopolymers comprised of nucleotide monomers that are composed of three moieties, a five-carbon sugar, a phosphate group, and a nitrogenous base.

Where is deoxyribose on a nucleotide?

This nucleotide contains the five-carbon sugar deoxyribose (at center), a nucleobase called adenine (upper right), and one phosphate group (left).

What are the 4 nucleotide of DNA?

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

Is RNA a nucleotide?

A nucleotide is the basic building block of nucleic acids. RNA and DNA are polymers made of long chains of nucleotides. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

Is glucose present in DNA?

Note: DNA is a short form for deoxyribose nucleic acid. The backbone of DNA is built of alternating sugar and phosphate units. Ribose is a monosaccharide and has five carbon atoms. Glucose is hexose and contains six carbon atoms.

What is the formula for Deoxyribose?

Deoxyribose, or more precisely 2-deoxyribose, is a monosaccharide with idealized formula H−(C=O)−(CH 2)−(CHOH) 3−H. Its name indicates that it is a deoxy sugar, meaning that it is derived from the sugar ribose by loss of an oxygen atom.

What is the difference between ribose and deoxyribose?

The key difference between deoxyribose and ribose is that the deoxyribose, the sugar found in DNA, lacks oxygen atom on carbon 2 of the sugar ring while ribose, the sugar found in RNA, has a hydroxyl group on carbon 2 of the sugar ring. Nucleic acids are probably the most fundamental biological molecules.

What is the chemical formula for Deoxyribose?

Deoxyribose is formed by the replacement of the hydroxyl group at the position, the carbon furthest from the attached carbon with hydrogen, leading to the net loss of an oxygen atom. Ribose has the chemical formula C 5H 10O 5. Thus, deoxyribose has the chemical formula C 5H 10O 4.

What is the biological function of deoxyribose?

Deoxyribose in DNA. As mentioned above, deoxyribose is a component of the DNA chain which gives it great biological importance. The DNA molecule (deoxyribonucleic acid), is the main repository of genetic information in life.
