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.

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 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.
A DNA nucleotide is composed of a sugar, called ~, a phosphate group and a nitrogenous base. A polynucleotide is a nucleic acid molecule consisting of a long chain of nucleotides.

Nucleoside In molecular biology; a molecule composed of a sugar (2' ~ 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 ~.
DNA (~ 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 ~ and ribose are the two sugars. ~ 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 ~ (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 ~ (this indicates the 3' terminal).
The ~ sugar ring.
Is the ~ ring flat or puckered?

A nucleotide is made up of a nitrogenous base and a phosphate group covalently bonded to a five-carbon sugar molecule (~ 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 ~ 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 (~ 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-~ 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 ~ 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 ~ 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).
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 (~ 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 ~. See also base.
Pathogen: a disease-causing agent (e.g. bacteria, virus, insect, etc.).
It would be more accurate to label the nucleotide deoxyadenosine monophosphate, as it includes the sugar ~ 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.
nucleosides - compound composed of a purine or pydimidine base linked to either a ribose or ~ sugar. DNA and RNA are not polymers of nucleosides.
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 ~. Sometimes compounds containing other elements are also counted as carbohydrates (e.g.
(1.) the sugar used in RNA is ribose, which contains one less oxygen atom than the ~ in DNA, and: ...
