Difference Between Sanger And Next Generation Sequencing

Improved Essays
Biology is a huge subject with many sub branches, application and tools that have helped in the improvement of humanity. One of the many Biology branches, that is currently helping in medicine and other areas related to health, and biology, is the Bioinformatics. The way it is doing it is by improvement and be able to sequencing DNA (genome). Bioinformatics can be describes as a science tool in which use computer technology to analyze, collect, “storage, and retrieval of genomic data” (American Heritage Dictionary). There are different ways to sequence the genome or DNA, store and evaluate the information obtained. Some of the methods are Sanger and Next Generation Sequencing, also known as hierarchical and whole-genome shotgun sequencing. …show more content…
Making it a long process that produces 700 base pairs (bp) in an hour. In the other hand, Next Generation involves shorter steps, it amplifies the genome fragment by PCR and then determine the sequence by observing the addition of nucleotides as it is synthesized from the template. Also, most of the steps are performed by machine. A major difference between Sanger and Next Generation Sequencing is the read length produce, Next Generation produces 75 to 400 bp between 7 hours to 10 days and there is more analysis to do on Next Generation than Sanger. This technology is comprised of various platforms which include nanopore technology, Illumina and Roche/454. More genome data are now being produced by Next gene sequencing than Sanger DNA sequencing. (mention Any …show more content…
Epigenetics “refers to external modifications to DNA that turn genes "on" or "off." These modifications do not change the DNA sequence, but instead, they affect how cells "read" genes.” () Gene expression can be affected by the environment and the life style of the organism. Exploring the genome of different kinds of Drosophila can gave a better understanding of it changes or evolution of the dot chromosomes. Since Sager is an expensive tools and Roche/454 has more coverage but creates mononucleotide runs, also known as homopolymer runs, a hybrid assembly was made to our, and GEP, projects. The hybrid assembly, which will be our sequence, consists of data from Roche/454 and

    By having a thicker gel, smaller segments can move better and not be cleared out by bigger segments. Polymerase Chain Reaction (PCR) is used to replicate DNA. In Lab 5, we created PCR amplicons by collecting our own DNA through our cheek cells, adding Taq DNA polymerase, dNTPs, primer, and a proper buffer solution into a PCR tube.…

    Introduction: The Drosophila melanogaster, otherwise known as the common fruit fly has been a useful organism to the field of genetics. It has a relatively short generation time of approximately 10 days at 25 degrees Celsius, and yields a large amount of offspring. This results in large amounts of data over a short time period.…

    In a perfect world, evolution would vote against all of the disease and harmful genes that ever existed in humans and other life-forms. After millions of years of selective processes geared toward survival, why is surviving still such a struggle? Dr. Sharon Moalem’s Survival of the Sickest deals entirely with the study of evolution and a variety of theories related to how humans, genes, microbes, viruses, and animals have evolved to survive through mutation and natural selection. Each chapter begins with anecdotes that lead into a well-researched collection of evidence and theories related to different aspects of evolution. First, Dr. Moalem covered the history of hemochromatosis, a disease where too much iron builds up in the blood of the…

    Introduction: Drosophila melanogaster, which commonly is known as fruit fly, has been used in genetic study for centuries. They tend to give birth to a large amount of offspring while their life cycles and generations are short. Their genes can be mutated easily by radiation or mutagens in food. They have four large chromosomes with approximately fourteen thousands genes. As expected, human have several times more gene than D. melanogaster, however, we have almost the same number of gene families.…

    In this new technology, there are two approaches involve which are phospholinked nucleotides and Zero Waveguide (ZMW). The sequencing begins with a single DNA polymerase is immobilized at the bottom of a reaction cell and the reaction called a ZMW (Zero Mode Waveguide). DNA is replicated by enzymes called DNA polymerase which is efficiently duplicate the entire genomes in minutes by reading the DNA and sequentially building a complementary with matching building blocks called nucleotides. DNA polymerase bound to the DNA template is anchored to the bottom glass surface of ZMW. In this sequencing, a phospholinked dNTP is used and each dNTP contains a different fluorophore.…

    In 2005, new sequence technique, which known as next-generation or second generation sequencing, was emerged after three decades of Sanger sequencing dominance. The new technique, 454 pyrosequencing, has completely new mechanism compared with the previous one, where this technique depended on series of enzymatic steps that including four enzymes polymerase, ATP sulfurylase, luciferase and apyrase under pyrosequencing mechanism. The name 454 pyrosequencing derived from pyrophosphate that realised from incorporation of nucleotide to new DNA strand during sequencing run. Four main steps summarises the entire sequencing technology, that have described in 454 sequencing website, (i) DNA library preparation, (ii) Emulsion PCR, (iii) Sequencing-by-synthesis…

    The study of heritable changes in gene expression without a change in DNA sequence is defined as epigenetics. Epigenetics covers a variety of areas in life science such as, biological sciences, effect of pollutants, etc.. The study of epigenetics is important because it allows researchers to trace the causes of certain diseases, follow the effects pollution has in humans and understand how eating habits can alter a person's appearance. Epigenetic modifications can affect the level of expression and timing of specific genes. This in turn causes those genes to be on when they should be off or vice versa, the alteration may contribute to the formation of disease or the progression of it .…

    Fruit flies (Drosophila Melanogaster – Figure 1) have been a model system for research on all levels of biology. Their small size, relatively cheap pricing, and short lifespans make them easy to care for and breed. More importantly, the fruit fly genome is completely sequenced, with 77% of searched human genetic disease genes matching 548 unique drosophila gene sequences (Reiter et al., 2001). This relationship between the genome of fruit flies and that of humans ensures fruit flies are important tools for elucidating an understanding on a range of human afflictions, including serious conditions such as Alzheimer’s and Huntington’s disease (Greenspan and Dierick, 2004). With such a rich genome, the fruit fly offers hope to thousands of people suffering from epigenetic conditions, and may even move on too more.…

    Whole genome sequencing (WGS) was used before exome sequencing. WGS does exactly as the name suggests, it sequences the whole genome includes the noncoding regions. Exome sequencing has many advantages over WGS. Exome sequencing is much cheaper than WGS, coming in at a total of about $500 (Perkel, 2013, p. 262). Since the exon is much smaller than the whole genome, results are obtained at a faster rate and higher resolution than WGS.…

    DNA sequencing and information is useful in many fields of science and technology. DNA ideally can be used to identify specific organisms because most organisms don’t possess the same DNA.The use of DNA to try to identify specific organisms is called DNA fingerprinting. DNA fingerprinting involves creating a DNA fingerprint using gel electrophoresis, which is the process by which DNA is broken down into fragments and then sorted by positive electrodes (after negative electrodes repel them from the other side. And as this happens the DNA strands for lines of different lengths resulting in an identifiable pattern. There are wide array of uses for DNA fingerprinting.…
