Nucleotides made of thymine

Five nucleotides are commonly used in biochemistry and genetics. Each nucleotide is a polymer made up of three parts:. The five bases are adenine, guanine, cytosine, thymine, and uracil, which have the symbols A, G, C, T, and U, respectively. The name of the base is generally used as the name of the nucleotide, although this is technically incorrect. The bases combine with the sugar to make the nucleotides adenosine, guanosine, cytidine, thymidine, and uridine.

Nucleotides are named based on the number of phosphate residues they contain. For example, a nucleotide that has an adenine base and three phosphate residues would be named adenosine triphosphate ATP. If the nucleotide has two phosphates, it would be adenosine diphosphate ADP.

If there is a single phosphate, the nucleotide is adenosine monophosphate AMP. Although most people learn only the five main types of nucleotides, there are others, including, for example, cyclic nucleotides e.

The bases can also be methylated to form different molecules. DNA uses adenine, thymine, guanine, and cytosine, while RNA uses adenine, guanine, and cytosine but has uracil instead of thymine. The helix of the molecules forms when two complementary bases form hydrogen bonds with each other.

Guanine and cytosine complement each other G-C. To form a nucleotidea base connects to the first or primary carbon of ribose or deoxyribose.

The number 5 carbon of the sugar connects to the oxygen of the phosphate group. In DNA or RNA molecules, a phosphate from one nucleotide forms a phosphodiester bond with the number 3 carbon in the next nucleotide sugar. The bases take one of two forms.

Purines consist of a double ring in which a 5-atom ring connects to a 6-atom ring. Pyrimidines are single 6-atom rings.Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers deoxyribonucleic acid DNA and ribonucleic acid RNAboth of which are essential biomolecules within all life-forms on Earth.

Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver. Nucleotides are composed of three subunit molecules: a nucleobasea five-carbon sugar ribose or deoxyriboseand a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanineadeninecytosine and thymine ; in RNA, uracil is used in place of thymine. Nucleotides also play a central role in metabolism at a fundamental, cellular level. They provide chemical energy—in the form of the nucleoside triphosphatesadenosine triphosphate ATPguanosine triphosphate GTPcytidine triphosphate CTP and uridine triphosphate UTP —throughout the cell for the many cellular functions that demand energy, including: amino acidprotein and cell membrane synthesis, moving the cell and cell parts both internally and intercellularlycell division, etc.

In experimental biochemistrynucleotides can be radiolabeled using radionuclides to yield radionucleotides. A nucleo tide is composed of three distinctive chemical sub-units: a five-carbon sugar molecule, a nucleobase —which two together are called a nucleo side —and one phosphate group.

With all three joined, a nucleotide is also termed a "nucleo side mono phosphate", "nucleoside di phosphate" or "nucleoside tri phosphate", depending on how many phosphates make up the phosphate group. In nucleic acidsnucleotides contain either a purine or a pyrimidine base—i. Individual phosphate molecules repetitively connect the sugar-ring molecules in two adjacent nucleotide monomers, thereby connecting the nucleotide monomers of a nucleic acid end-to-end into a long chain.

These chain-joins of sugar and phosphate molecules create a 'backbone' strand for a single- or double helix.

In any one strand, the chemical orientation directionality of the chain-joins runs from the 5'-end to the 3'-end read : 5 prime-end to 3 prime-end —referring to the five carbon sites on sugar molecules in adjacent nucleotides. In a double helix, the two strands are oriented in opposite directions, which permits base pairing and complementarity between the base-pairs, all which is essential for replicating or transcribing the encoded information found in DNA.

Nucleic acids then are polymeric macromolecules assembled from nucleotides, the monomer-units of nucleic acids. Adenine forms a base pair with thymine with two hydrogen bonds, while guanine pairs with cytosine with three hydrogen bonds. In addition to being building blocks for the construction of nucleic acid polymers, singular nucleotides play roles in cellular energy storage and provision, cellular signaling, as a source of phosphate groups used to modulate the activity of proteins and other signaling molecules, and as enzymatic cofactorsoften carrying out redox reactions.

Signaling cyclic nucleotides are formed by binding the phosphate group twice to the same sugar molecule, bridging the 5'- and 3'- hydroxyl groups of the sugar. NADPa dinucleotide enzymatic cofactor. FADa dinucleotide enzymatic cofactor in which one of the ribose sugars adopts a linear configuration rather than a ring.

Nucleotides can be synthesized by a variety of means both in vitro and in vivo. In vitro, protecting groups may be used during laboratory production of nucleotides. In vivo, nucleotides can be synthesized de novo or recycled through salvage pathways.

The liver is the major organ of de novo synthesis of all four nucleotides. De novo synthesis of pyrimidines and purines follows two different pathways.

Pyrimidines are synthesized first from aspartate and carbamoyl-phosphate in the cytoplasm to the common precursor ring structure orotic acid, onto which a phosphorylated ribosyl unit is covalently linked. Purines, however, are first synthesized from the sugar template onto which the ring synthesis occurs. For reference, the syntheses of the purine and pyrimidine nucleotides are carried out by several enzymes in the cytoplasm of the cell, not within a specific organelle.

Nucleotides undergo breakdown such that useful parts can be reused in synthesis reactions to create new nucleotides. Next, aspartate carbamoyltransferase catalyzes a condensation reaction between aspartate and carbamoyl phosphate to form carbamoyl aspartic acidwhich is cyclized into 4,5-dihydroorotic acid by dihydroorotase.

The latter is converted to orotate by dihydroorotate oxidase. The net reaction is:.The others are adenineguanineand cytosine. Thymine is also known as 5-methyluracil, a pyrimidine nucleobase.


In RNAthymine is replaced by the nucleobase uracil. Thymine was first isolated in by Albrecht Kossel and Albert Neumann from calves' thymus glands, hence its name. As its alternate name 5-methyluracil suggests, thymine may be derived by methylation of uracil at the 5th carbon. In RNAthymine is replaced with uracil in most cases. In DNA, thymine T binds to adenine A via two hydrogen bonds, thereby stabilizing the nucleic acid structures. Thymine combined with deoxyribose creates the nucleoside deoxythymidinewhich is synonymous with the term thymidine.

Thymidine can be phosphorylated with up to three phosphoric acid groups, producing dTMP d eoxy t hymidine m ono p hosphatedTDPor dTTP for the d i- and t ri- phosphates, respectively. One of the common mutations of DNA involves two adjacent thymines or cytosine, which, in presence of ultraviolet lightmay form thymine dimerscausing "kinks" in the DNA molecule that inhibit normal function.

Thymine could also be a target for actions of 5- fluorouracil 5-FU in cancer treatment. Substitution of this analog inhibits DNA synthesis in actively dividing cells. Thymine bases are frequently oxidized to hydantoins over time after the death of an organism. In MarchNASA scientists reported that, for the first time, complex DNA and RNA organic compounds of lifeincluding uracilcytosine and thymine, have been formed in the laboratory under outer space conditions, using starting chemicals, such as pyrimidinefound in meteorites.

Pyrimidine, like polycyclic aromatic hydrocarbons PAHsanother carbon-rich compound, may have been formed in red giants or in interstellar dust and gas clouds, according to the scientists.

Thymine likely formed within some meteorite parent bodies, but may not have persisted within these bodies due to an oxidation reaction with hydrogen peroxide. From Wikipedia, the free encyclopedia.

American author, inventor and futurist Raymond Kurzweil has become well known for his predictions about artificial intelligence and the human species, mainly concerning the technological singularity.

He predicts that Artificial Intelligence would outsmart the human brain in computational capabilities by mid-21st century. His first book, The Age of Intelligent Machines, published in 1990, put forth his theories on the results of the increasing use of technology and predicted the explosive growth in the internet, among other predictions.

Later works, 1999's The Age of Spiritual Machines and 2005's The Singularity is Near outlined other theories including the rise of clouds of nano-robots (nanobots) called foglets and the development of Human Body 2.

Kurzweil's first book, The Age of Intelligent Machines was published in 1990. It forecast the demise of the Soviet Union due to new technologies such as cellular phones and fax machines disempowering authoritarian governments by removing state control over the flow of information.

He also stated that the Internet would explode not only in the number of users but in content as well, eventually granting users access "to international networks of libraries, data bases, and information services". The third and final section of the book is devoted to elucidating the specific course of technological advancements Kurzweil believes the world will experience over the next century.

Titled "To Face the Future", the section is divided into four chapters respectively named "2009", "2019", "2029", and "2099". For every chapter, Kurzweil issues predictions about what life and technology will be like in that year.

The device was portable, but not the cheap, pocket-sized device of the prediction. While this book focuses on the future of technology and the human race as The Age of Intelligent Machines and The Age of Spiritual Machines did, Kurzweil makes very few concrete, short-term predictions in The Singularity Is Near, though longer-term visions abound.

Kurzweil predicted that, in 2005, supercomputers with the computational capacities to simulate protein folding will be introduced. In 2010, a supercomputer simulated protein folding for a very small protein at an atomic level over a period of a millisecond. The protein folded and unfolded, with the results closely matching experimental data.
