Structurally simple carbohydrate. Deoxyribose is an important part of deoxyribonucleic acid.
By convention, the carbon atoms are numbered with primes ('). In nucleotides, and nucleic acids, the 5' carbon is linked to the phosphate, and the 1' carbon to the base.
Deoxyribose, which has a hydrogen atom attached to its #2 carbon atom (designated 2')
Ribose, which has a hydroxyl group atom there
Deoxyribose-containing nucleotides, the deoxyribonucleotides, are the monomers of DNA.
deoxyribose Five-carbon sugar found in nucleotides of DNA. PICTURE
depth diversity gradient The increase in species richness with increasing water depth until about 2000 meters below the surface, where species richness begins to decline.
deoxyribose the five-carbon carbohydrate attached to purine or pyrimidine bases within DNA molecules.
dermal tissue the tissue that functions to protect the plant from injury and water loss and covers the outside of the plant.
Deoxyribose - A five-membered sugar ring that lacks a hydroxyl group at one position, and is the sugar group for DNA.
deoxyribose 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 - deoxyribose.
a base - either adenine, guanine, thymine or cytosine.
DNA is a macromolecule polymer made of subunits called nucleotides. The nucleotides are arranged in two chains which are coiled into a spiral shape called a double helix.
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 analogueSynthetic nucleosides that are similar to nucleosides but differ at a key location.

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)). The link is through the 1' carbone atom in ribose or deoxyribose.
DNA (deoxyribose nucleic acid) is the genetic material of all cells. RNAs (ribose nucleic acid) which are closely related, are copies of the genes which are sent out to the cytoplasm of the cell to direct the synthesis of proteins for which the genes code.
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 deoxyribose 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 deoxyribose (this indicates the 3' terminal).
The deoxyribose sugar ring.
Is the deoxyribose 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.
Location of GC and AT base pairs in DNA double helix.
The only difference between the sugars is the lack of an oxygen atom on carbon two in deoxyribose.
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. In its native state, DNA is a double helix of two antiparallel strands held together by hydrogen bonds between complementary purine and pyramidine bases. (Figure 4-6) ...
Nucleotides are constituted by one molecule of sugar (deoxyribose in DNA and ribose in RNA) bound to one molecule of phosphate and to one nitrogen-containing base (adenine, uracil, cytosine or guanine, in RNA, and adenine, thymine, cytosine and guanine, in DNA).
An enzyme which cleaves phosphate-deoxyribose 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.
The sugar is different since Ribose replaces the Deoxyribose in the nucleotide. Most of RNA has a linear structure and not that of a ladder. RNA's functions vary from taking the code for a protein to the ribosome(m-RNA) to bringing in the correct amino acids to produce the protein (t-RNA).
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).
It would be more accurate to label the nucleotide deoxyadenosine monophosphate, as it includes the sugar deoxyribose and a phosphate group in addition to the nitrogenous base. However, the more familiar "adenine" label makes it easier for people to recognize it as one of the building blocks of DNA.
Pure carbohydrates contain carbon, hydrogen, and oxygen atoms, in a 1:2:1 molar ratio, giving the general formula CnH2nOn. However, many important carbohydrates deviate from this, such as deoxyribose. Sometimes compounds containing other elements are also counted as carbohydrates (e.g.
