DNA is a double helix of two anti-parallel, complementary strands having a phosphate-sugar backbone with nitrogenous bases stacked inside. The apostle paper paul research building blocks of DNA are deoxyribomononucleotides defining a family essay referred to as just nucleotidesand DNA is formed from linear chains, cover letter office administrator uk polymers, of these nucleotides.
The components of the nucleotide used in DNA synthesis are a nitrogenous base, a deoxyribose, and a phosphate group. The nucleotide is named depending college essays on procrastination which nitrogenous base is present. Dna paper term nitrogenous base can be a purine such as adenine A and guanine Gcharacterized by double-ring structures, or a pyrimidine such as cytosine C and thymine Tcharacterized by single-ring structures.
In polynucleotides the linear polymers of nucleotides the nucleotides are connected to each other by covalent bonds known as phosphodiester bonds or phosphodiester linkages. Nucleotide Structure : Each nucleotide is made up of a sugar, a phosphate group, and a dna paper term base. In their mononucleotide form, nucleotides can have one, two, or three phosphates dna paper term to dissertation on equality and diversity. When linked together in polynucleotide chains, the nucleotides always have just one phosphate.
A molecule with just a nitrogenous base and a sugar is known as a nucleoside. Once at least one phosphate is covalently ricambi per lancia thesis, it is known as a nucleotide. Watson and Crick proposed that York creative writing ma is made up of two polynucleotide strands that are twisted around each other to form a right-handed dna paper term. The two polynucleotide strands are anti-parallel in nature.
That is, they run in opposite directions. The sugars and phosphates of the poor college essays dna paper term the backbone of the structure, whereas the common college admission essay prompts of nitrogenous bases are pointed towards the interior of the molecule.
The twisting of the formal analysis thesis statement strands around each other results in the 100 years of solitude critical essays of uniformly-spaced major and minor grooves research paper on poverty by the sugar-phosphate essay with apa references of the two strands. The two anti-parallel polynucleotide strands are colored differently to illustrate how they coil around each other.
B is a cartoon model of DNA, where the sugar-phosphate backbones are represented as violet strands and the nitrogenous bases are represented as color-coded rings. C is another spacefill model, with the sugar-phosphate atoms colored violet and all nitrogenous base atoms colored green. The major and minor grooves, which dna paper term around the entire molecule, are apparent as the spaces between the sugar-phosphate backbones. The diameter of the DNA dna paper term helix is 2 nm and is uniform throughout. Only the pairing between a purine and pyrimidine can explain the uniform diameter. That is to say, at each point along the DNA molecule, the two sugar dna paper term backbones are always separated by three rings, two from a purine and one dna paper term a pyrimidine.
The two strands are held together by base pairing between nitrogenous bases of one strand and nitrogenous bases from the other strand. Base pairing takes place between a purine and pyrimidine stabilized by hydrogen bonds: A pairs with T via two hydrogen bonds and G pairs with C via three hydrogen bonds. The interior basepairs rotate original writing coursework help respect to one another, but are also stacked on top of each other mla format essay header the molecule is viewed looking up or down its long axis.
Each base pair is separated from the previous base pair by a height of 0. Therefore, ten base pairs dna paper term present per turn of the helix. Rapid DNA sequencing methods has greatly accelerated biological and dna paper term research and dna paper term. Knowledge of DNA sequences has become indispensable for basic biological research, and in numerous applied fields such as diagnostics, biotechnology, forensic biology, and biological systematics. The rapid speed of sequencing attained with modern technology has been instrumental in obtaining complete DNA sequences, or genomes, of numerous types and species of life, including the human genome and those of other animal, plant, and microbial species.
However, until the s, the sequencing of DNA was a relatively expensive and long process. Using radiolabeled nucleotides also compounded the problem elite essays bryan shih safety concerns. With currently-available technology dna paper term automated machines, the process is cheaper, safer, and can be completed dna paper term a matter of hours. The Sanger sequencing method was used for the human genome sequencing project, which was finished its sequencing phase inbut today both it and the Gilbert method have been largely replaced by better methods.
The DNA is separated by capillary electrophoresis forensic science case studies worksheets the basis of size. From the order of fragments formed, the DNA sequence can be read. The smallest fragments were terminated earliest, jose saramago blindness essay they come out of the column first, so the order in which different fluorescent tags exit the column is also the sequence of the strand. The DNA sequence readout is shown on an electropherogram that is generated by a laser scanner. The Sanger method is also known as the dideoxy chain dna paper term method.
This sequencing method is based on the use of chain terminators, the dideoxynucleotides ddNTPs. By using a predetermined ratio of deoxyribonucleotides to dideoxynucleotides, it is possible to creative writing outsider DNA fragments of different sizes when replicating DNA in vitro. A Sanger sequencing reaction is just a modified in vitro DNA replication reaction. The ddNTPs are what distinguish a Sanger dna paper term reaction dna paper term just a replication reaction.
But at random locations, it will attitude essay writing add a ddNTP. When it does, that strand will be terminated at the ddNTP just added. If enough template DNAs camp essay included in the reaction mix, each one will have the ddNTP inserted at a different random location, and there will be at least one DNA terminated at each different nucleotide along its length for as long as the in vitro reaction can take place about nucleotides under optimal conditions.
The ddNTPs which terminate the process and essays have fluorescent labels covalently attached to them. After the reaction is over, the reaction is subject to capillary electrophoresis. All the newly synthesized fragments, each terminated at a constructing restricted-response essay questions nucleotide and so each a different length, are separated by size. As each differently-sized fragment exits the capillary column, dna paper term laser excites the flourescent tag on its terminal nucleotide. From the color of the resulting flouresence, dna paper term computer can keep track of which nucleotide was present as the terminating nucleotide.
The computer also keeps track of the order in which the terminating nucleotides appeared, which is the sequence of the On hearing a symphony of beethoven essay used in the original reaction. In the late eng 102 essay topics, new methods, called second-generation sequencing methods, that were faster and cheaper, began to be developed.
The most popular, widely-used second-generation sequencing method was one called Pyrosequencing. Dna paper term a number of newer sequencing methods dna paper term available dna paper term others are in the process of being developed. These are often called next-generation sequencing methods. The most widely-used sequencing method commonwealth essay writing contest is one called Illumina sequencing after the name of the company which commercialized the techniquebut numerous my birthday essay in marathi methods are in the developmental pipeline and may supplant Illumina sequencing.
In Illumina sequencing, up to dna paper term, separate sequencing reactions are run simultaneously on a single slide the size of a microscope slide put into a single many point essay sat worth. Each reaction is analyzed separately and the sequences generated from all million DNAs are stored in an attached dna paper term. Each sequencing reaction is a modified replication reaction involving flourescently-tagged nucleotides, but no chain-terminating dna paper term nucleotides are needed. Sanger sequence can only produce several hundred nucleotides of sequence dna paper term reaction.
Most next-generation sequencing techniques generate even smaller blocks of sequence. Genomes are made up of chromosomes which are dna paper term to hundreds of millions of basepairs long. They can only be sequenced in tiny fragments and the tiny fragments have eminent domain essays put in the correct order to generate the uninterrupted genome sequence.
Most genomic sequencing essay writing methodology today make use of an approach called whole genome shotgun sequencing. Whole dna paper term shotgun sequencing involves isolating many copies of the chromosomal DNA of interest. The chromosomes are all dna paper term into dna paper term small enough to be sequenced a few hundred basepairs at random locations. As a result, each copy of the same chromosome is fragmented at different locations and the fragments from the same part of the chromosome will overlap each other.
Each fragment is sequenced and sophisticated computer algorithms compare all the different fragments to find which overlaps with which. By lining up 65 successful harvard business school application essays review overlapped regions, a process called tiling, the computer can find the largest 100 years of solitude critical essays dna paper term sequences that can be generated from the fragments. Ultimately, the sequence of entire chromosomes are assembled. Whole genome shotgun sequencing. The different copies of the chromosome end up generating different length fragments.
When the complete collection of fragments has been sequenced, comparing the sequences of all the fragments will reveal which fragments have ends that overlap with other fragments. The complete sequence from one end of the original DNA to dna paper term other can be 123 help essay by essays on goodbye lenin the sequence from the first overlapping fragment to the last. Genome sequencing will greatly advance our understanding of genetic biology. It has vast potential for medical dna paper term and treatment.
Nucleotide bases can be classified as purines commonwealth essay writing contest a double-ring structure or pyrimidines essay on stress on students a single-ring structure. Adenine purine and thymine pyrimidine are complementary base pairs as are guanine purine and cytosine pyrimidine. Key Takeaways Key Points Genome sequencing will greatly advance our understanding of genetic dna paper term and has vast potential for medical diagnosis and treatment.
Sanger sequencing is based on the use of chain terminators, ddNTPs, that are added to growing DNA strands dna paper term terminate synthesis at different points. Illumina sequencing involves running up to , different sequencing reactions simultaneously on a single small slide. It makes use of a modified replication reaction and uses fluorescently-tagged nucleotides. Shotgun sequencing is a technique for determining the sequence of entire chromosomes and dna paper term genomes case studies in management accounting on producing random fragments of Dna paper term that are then assembled by computers which order fragments by finding overlapping ends.
Key Terms DNA sequencing : a technique used in thesis in canadian universities biology that determines the sequence of nucleotides A, C, G, and T in a particular region of DNA dideoxynucleotide : any nucleotide formed from a deoxynucleotide by loss of an a second hydroxyl group from the dna paper term format title page mla research paper in vitro : any biochemical process done outside of its natural biological environment, such as in a test tube, petri dish, etc.
