DNA Sequencing -Next-generation dna sequencers have sufficient power analyze simultaneously DNAs from many different specimens, a practice known as multiplexing. Compressed Genotyping, DNA high throughput sequencing for multiplexed specimen analysis.
The success of dna sequencing reaction depends upon the quality and quantity of DNA sequencing template. The capillary system is very sensitive to contaminants such as proteins, RNA and residual salts. Not only is the quality of result affected by such contaminants but the presence of proteins and high concentrations of DNA sequencing can reduce the life of the capillary array.
DNA sequencing results have only a fairly limited number of causes. To help in the troubleshooting of sequencing problems we have created a series of guides for identifying the most common causes of various sequencing problems.For detailed information on DNA template preparation, DNA template quality and quantity, primer design and quantitation, we can refer Performing DNA Sequencing Reactions.
The key to DNA sequencing is the PCR. The DNA that is extracted from patient muscle tissue has to be amplified – making it available in large amounts. Dystrophin, the gene is actually one of the longest.After running the PCR on the Thermocycler, the amplified DNA segments are run through a gel electrophoresis reaction.

The DNA sequencingundergoes a couple of protocols in order to prepare it for the sequencer. The steps include the Exonuclease, Sequencing, Ethanol/Sodium Acetate Precipitation and the Denaturation reactions. The Analyser has a laser which causes the applied dye on the four nucleotides (A-T-C-G) to illuminate different colors of the visible light spectrum. The colors are then recorded and sent to the computer for further analysis. A genius piece of technology. Inorder to prepare the DNA for sequencing, it had to go through an Exonuclease Reaction, Ethanol/Sodium Acetate Precipitation Reaction and a Denaturation reaction in dna sequencing.
