Deoxyribose
Structurally simple carbohydrate. Deoxyribose is an important part of deoxyribonucleic acid.

dermal tissue the tissue that functions to protect the plant from injury and water loss and covers the outside of the plant.

- A five-membered sugar ring that lacks a hydroxyl group at one position, and is the sugar group for DNA.

Deoxyribose
A type of sugar that is one component of DNA (deoxyribonucleic acid).

A 5-carbon sugar having 1 oxygen atom less than ribose; a component of deoxyribonucleic acid (DNA).
dependency ratio The number of nonworking members compared to working members for a given population.

The deoxyribose sugar of the DNA backbone has 5 carbons and 3 oxygens.
The carbon atoms are numbered 1', 2', 3', 4', and 5' to distinguish from the numbering of the atoms of the purine and pyrmidine rings.

a sugar - .
a base - either adenine, guanine, thymine or cytosine.

DNA encodes the information needed to build proteins, to regulate physiological processes and maintain homeostasis in our bodies. The basic chemical components of DNA are phosphate, deoxyribose (a sugar) and 4 nitrogenous bases: adenine (A), ...

An organic acid and polymer composed of four nitrogenous bases--adenine, thymine, cytosine, and guanine linked via intervening units of phosphate and the pentose sugar .

Compounds consisting of a purine (adenine or guanine) or pyrimidine (thymine or cytosine) attached to ribose (in RNA) or deoxyribose (in DNA) at the 11 carbon.

Nucleoside In molecular biology; a molecule composed of a sugar (2' deoxyribose in DNA; ribose in RNA) which is linked to a purine (adenine or guanine) or a pyrimidine (thymine (DNA), cytidine or uridine (RNA)).

DNA ( nucleic acid) is the genetic material of all cells. RNAs (ribose nucleic acid) which are closely related, ...

Well deoxyribose and ribose are the two sugars. Deoxyribose can you guess which one uses that? You're right! ...

Each nucleotide sub-unit consists of a phosphate, a sugar, and one of the four nitrogenous nucleobases. The purine bases adenine (A) and guanine (G) are larger and consist of two aromatic rings.

At one end of each strand there is a phosphate group attached to the carbon atom number 5 of the deoxyribose (this indicates the 5' terminal) and at the other end of each strand is a hydroxyl group attached to the carbon atom number 3 of the ...

The sugar ring.
Is the ring flat or puckered?
Location of the sugar in the DNA double helix.
Are the two strands of DNA parallel or anti-parallel?
Structure of GC and AT base pairs.

A nucleotide is made up of a nitrogenous base and a phosphate group covalently bonded to a five-carbon sugar molecule (deoxyribose in DNA and ribose in RNA). purines and pyrimidines.

The only difference between the sugars is the lack of an oxygen atom on carbon two in .
Because the atoms in both the nitrogenous base and the sugar are numbered, the sugar atoms have a prime after the number to distinguish them.

Long linear polymer, composed of four kinds of deoxyribose nucleotides, that is the carrier of genetic information.

Nuclease
An enzyme which cleaves phosphate- bonds within (endonuclease) or at the end (exonuclease) of a nucleotide sequence. Nucleases usually recognize a specific substrate, such as single- or double-stranded DNA or RNA.

This enzyme severs the tie between the base and the deoxyribose group. This reaction is similar to a process that occurs spontaneously, that is without an enzyme. The bond between the base and the sugar can be hydrolyzed and the base lost.

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

A subunit of DNA or RNA consisting of a nitrogenous base (purine in adenine and guanine, pyrimidine in thymine, or cytosine for DNA and uracil cytosine for RNA), a phosphate molecule, and a sugar molecule (deoxyribose in DNA and ribose in RNA).

Pentose sugar: A sugar molecule containing five carbon atoms. E.g.: .
Phage: A virus which infects a bacterial cell. Also called a Bacteriophage.

Nucleotide: the unit of DNA, consisting of one base, one phosphate molecule, and the sugar deoxyribose. See also base.
Pathogen: a disease-causing agent (e.g. bacteria, virus, insect, etc.).
