Nitrogenous bases can be added or react with the hemiacetal of the deoxyribose. Common bases added on are adenine and guanine (purine derivatives), and thymine, uracil, and cytosine (pyrimidine derivatives). When adenine is coupled with ribose, it is referred to as adenosine and when it is coupled with deoxyribose, it is referred to as deoxyadenosine. The 5'-triphosphate derivative of adenosine, also known as adenosine triphosphate (ATP), is vital for the transportation of energy molecules in the cell.. 2-deoxyribose and ribose nucleotides are usually foind as an unbranched 5'-3' polymer. The 3'-carbon of one monomer is attached to the 5'-carbon of another monomer, which is then attached to the 3'-carbon of another monomer, and can continue on for many millions of monomer units. These long polymer chains contain very different physical properties than those of small molecules, and so these polymers make up another division ...

*  ADENINE (6-AMINOPURINE)
Ribose is a pentose (five-carbon sugar) that is a component of the ribonucleic acid (RNA), where it alternates with phosphate groups to form the 'back-bone' of the RNA polymer and binds to nitrogenous bases. Ribose phosphates are components of the nucleotide coenzymes and are utilized by microorganisms in the synthesis of the amino acid histidine. Its close relative, deoxyribose, is a constituent of deoxyribonucleic acid (DNA), where it alternates with phosphate groups to form the 'back-bone' of the DNA polymer and binds to nitrogenous bases. The presence of deoxyribose instead of ribose is one difference between DNA and RNA. Ribose has one more oxygen atom in its molecule than deoxyribose. Ribose has a five member ring composed of four carbon atoms and one oxygen. Hydroxyl groups are attached to three of the carbons. The other carbon and a hydroxyl group are attached to one of the carbon atoms adjacent to the oxygen. In deoxyribose, the ...

*  The Kinematic Principle for Designing Deoxyribose Nucleic Acid Origami Mechanisms: Challenges and Opportunities1 | Journal of...
Deoxyribose nucleic acid (DNA) origami nanotechnology is a recently developed self-assembly process for design and fabrication of complex three-dimensional (3D) nanostructures using DNA as a functional material. This paper reviews our recent progress in applying DNA origami to design kinematic mechanisms at the nanometer scale. These nanomechanisms, which we call DNA origami mechanisms (DOM), are made of relatively stiff bundles of double-stranded DNA (dsDNA), which function as rigid links, connected by highly compliant single-stranded DNA (ssDNA) strands, which function as kinematic joints. The design of kinematic joints including revolute, prismatic, cylindrical, universal, and spherical is presented. The steps as well as necessary software or experimental tools for designing DOM with DNA origami links and joints are detailed. To demonstrate the designs, we presented the designs of Bennett four-bar and crank-slider linkages. Finally, a list of technical challenges such as design automation ...

*  Re: How is DNA better suited than RNA to carry genetic info?
To whom it may concern, The question was, how is DNA better suited than RNA to carry genetic information. Unfortunately, this is almost a philosophical question, since there really is no way of knowing for certain how the roles of DNA and RNA evolved. There may not BE an answer. Our evolutionary description of the role of DNA and RNA in biology comes from a number of observations, though we may never be able to say for certain how evolution has selected these functions. I'll assume you know enough about the chemistry of RNA and DNA to bypass some of the normal introductory discussion. The only chemical difference between RNA and DNA is the presence of 2'OH on the ribose of RNA. This has pronounced effects on the structure and stability of RNA as compared to DNA. The most obvious changes observed between ribose and deoxyribose sugars are in the distribution of sugar puckers; C3'-endo versus C2'-endo conformations dominate duplex RNA and DNA, respectively (Note that single deoxy- or ...

*  Structural Biochemistry/Nucleic Acid/Phosphate - Wikibooks, open books for an open world
The backbone of the DNA strand is made from alternating phosphate and sugar residues. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings.. As you noticed in the deoxyribose sugar, it does not contain a hydroxyl group on the 2' carbon. This absence of the hydroxyl group allows greater stability because the absence of hydroxyl group allows the 2' carbon to resist hydrolysis. This is one of the reasons why the hereditary material is stored in the DNA and not RNA. However, the net negative charge of the phosphate group must be stabilized by metal ions, such as magnesium or manganese.. ...

*  DNA, Chromosomes and the Genomes
DNA, chromosomes and the genome are three inter-related terms which represent the genetic composition of organisms. It is within the nucleus of a cell that the genome is housed and it includes both chromosomes and DNA.. The best way to differentiate these three interlinked terms is to start from the "smallest" term and move upwards. Thus, DNA is the most basic level within the genetic tree of terminology.. DNA is made up of nucleosides which are connected to each other with hydrogen bonds and are esterified to phosphate groups. These nucleosides contain a nitrogenous base and a deoxyribose sugar. There are four possible nitrogenous bases: adenine, guanine, thymine and cytosine. Adenine and guanine are most similar in structure and are called purines, whereas thymine and cytosine are pyrimidines.. Furthermore, each DNA molecule is made up of two anti-parallel strands. Each ...

The genome of an organism, is inscribed in DNA, or in some viruses RNA. The portion of the genome that codes for a protein or an RNA is referred to as a gene. Those genes that code for proteins are composed of tri-nucleotide units called codons, each coding for a single amino acid. Each nucleotide sub-unit consists of a phosphate, deoxyribose sugar and one of the 4 nitrogenous nucleotide bases. The purine bases adenine (A) and guanine (G) are larger and consist of two aromatic rings. The pyrimidine bases cytosine (C) and thymine (T) are smaller and consist of only one aromatic ring. In the double-helix configuration, two strands of DNA are joined to each other by hydrogen bonds in an arrangement known as base pairing. These bonds almost always form between an adenine base on one strand and a thymine on the other strand and between a cytosine base on one strand and a guanine base on the other. This means that ...

*  RNA and Proteins
... are two biological molecules which are dependent upon each other and play a role in controlling the functions of an organism. Furthermore, gene expression is controlled by RNA and proteins.. Essentially, RNA holds the information which is encoded within DNA and allows this information to be transcribed. Structurally, RNA and DNA differ. For one, RNA is made up of ribose sugars, instead of deoxyribose sugar, which is the sugar contained in the nucleosides of DNA strands. Secondly, the nucleotide thymine is not present in RNA strands and is replaced by another nucleotide called uracil. The last major difference is that RNA molecules are single-stranded.. There are also different types of RNA which are required during different processes. This includes:. ...

*  Replication - Biology Encyclopedia - cells, body, function, process, organisms, chromosomes, DNA, cycle, life
Replication is a huge task, whether in bacteria or in eukaryotes. There are several physical and biochemical challenges the cell must overcome. First, the site or sites at which to begin replication must be located and the proper enzymes collected there. Second, the double helix must be unwound to expose the two strands. This imposes twisting strain on the portions of the helix farther away from the unwinding site, much like untangling a twisted phone cord does, and those forces must be relieved to prevent breakage of the DNA strands. Complementary nucleotides must be put in place and linked to form a new strand, and errors must be checked and corrected. The orientation of the two strands poses an additional challenge. Because of the way the deoxyribose sugar is structured, the sugar, and hence the whole DNA strand, has a direction, an up versus down, so to speak. The two sides are oriented with up and down directions opposite, in a so-called antiparallel fashion. In biochemical terms, one ...

*  Life | Free Full-Text | Model of Biological Quantum Logic in DNA
The DNA molecule has properties that allow it to act as a quantum logic processor. It has been demonstrated that there is coherent conduction of electrons longitudinally along the DNA molecule through pi stacking interactions of the aromatic nucleotide bases, and it has also been demonstrated that electrons moving longitudinally along the DNA molecule are subject to a very efficient electron spin filtering effect as the helicity of the DNA molecule interacts with the spin of the electron. This means that, in DNA, electrons are coherently conducted along a very efficient spin filter. Coherent electron spin is held in a logically and thermodynamically reversible chiral symmetry between the C2-endo and C3-endo enantiomers of the deoxyribose moiety in each nucleotide, which enables each nucleotide to function as a quantum gate. The symmetry break that provides for quantum decision in the system is determined by the spin direction of an electron that has an orbital angular momentum that is ...

*  What is DNA?
The backbone of the DNA strand is made from alternating phosphate and sugar residues.The sugar in DNA is 2-deoxyribose, which is a pentose (five-carbon) sugar. The sugars are joined together by phosphate groups that form phosphodiester bonds between the third and fifth carbon atoms of adjacent sugar rings. These asymmetric bonds mean a strand of DNA has a direction. In a double helix the direction of the nucleotides in one strand is opposite to their direction in the other strand. This arrangement of DNA strands is called antiparallel. The asymmetric ends of DNA strands are referred to as the 5' (five prime) and 3' (three prime) ends, with the 5' end being that with a terminal phosphate group and the 3' end that with a terminal hydroxyl group. One of the major differences between DNA and RNA is the sugar, with 2-deoxyribose being replaced by the alternative pentose sugar ribose in RNA ...

Early in Biologia 2 is a treatment of the role of RNA, including the substitution of uracil for thymine, transcription as distinct from translation, and the functions of messenger, transfer, and ribosomal RNA. Polypeptides are described and peptide bonds mentioned, but not with the NH3-COOH dehydration synthesis. A typical vocab list: "Endoplasmic reticulum, Golgi apparatus, endocytosis, ribosomes, cellular membrane.". Then, "The synthesis proceeds only in the 5'-3' sense, which means that the chain that is being copied is read…." Also, (above) "DNA is formed by the union of five atoms: carbon (C), oxygen (O), hydrogen (H), nitrogen (N), and phosphorus (P). The DNA molecule can be decomposed into the monomers that form it.
