DNA sequencing enables the scientists to determine genome sequence. Human genome projects is the biggest example of DNA sequencing. When the human genome was sequenced back in 2001, many issue rose but now after many years, we can see it's impacts on medical and pharmaceutical research.
Second generation sequencing technology offers several advantages over traditional sequencing methods. These include higher throughput, faster processing times, lower costs, and the ability to sequence multiple samples simultaneously. Additionally, second generation sequencing technology provides more accurate and reliable results, making it a preferred choice for many research and clinical applications.
DNA sequencing has revolutionized the science of classifying organisms by providing a more accurate and objective way to understand evolutionary relationships between species. It has allowed for the reclassification of many organisms based on genetic similarities rather than physical characteristics, leading to a more precise and comprehensive system of classification. Additionally, it has revealed unexpected relationships between organisms that were not apparent before, leading to a better understanding of biodiversity.
NEED OF PRIMER IN PCR-It is because the polymerase enzyme we use in the PCR only extend a DNA strand but not initiate its synthesis. So, to initiate the synthesis of DNA strand onto a template strand we require primers.
In a sequencing reaction, typically two primers are used.
Companies that provides DNA sequencing services would include companies such as Operon, Nucleics, and Sanger Sequencing Service. There are many other companies who offer this service as well.
A common approach to DNA sequencing is through a process called Sanger sequencing, named after its inventory, Frederick Sanger. To describe the process simply, a sample of purified DNA is treated with a solution of enzymes, nucleotides, and terminators to duplicate the strands of DNA. As the DNA is being copied, it uses the nucleotides to form new strands of DNA and sometimes will add a terminator which stops the duplication process at varying lengths. The terminators are labeled with a radioactive or fluorescent chemical which allows them to be detected by a scanning machine. In capillary electrophoresis, the mixture of varying length DNA is separated in a very narrow tube and as each terminator passes by the detector, the sequence of the DNA bases can be read. For a more detailed description of the mechanics of Sanger sequencing, an internet search will yield many results.
Universal primers are really not 'universal' in the sense that they will bind to anything. Universal is kind of a misnomer. Really, universal primers are PCR/sequencing primers that bind to a sequence found in many plasmid cloning vectors, most of which are derived from pUC vectors (which in turn come from pBR322). These sequences were defined as good PCR and sequencing sites as they flank the multiple cloning site where an inserted DNA sequence would be put. You can now buy these universal primers from various companies. You can see that these primers are called universal because they can be used to amplify or sequence any insert that is put in the multiple cloning site.
Since the birth of DNA sequencing in the 70's several methods have been developed which have become increasingly more efficient. There are probably 10-15 mainstream ways of sequencing, although dye-terminator sequencing is the one primarily used
