NGS-Different-Sanger-Sequencing

How is NGS Different from Sanger Sequencing?

Introduction Sequencing DNA involves biochemical processes to ascertain the order (sequence) of nucleotides of DNA strands. Maxam-Gilbert and Sanger methods were developed over 40 years ago, but the Sanger method soon dominated the DNA sequencing arena. With this method, DNA is repeatedly copied resulting in DNA fragments of varying lengths. The ends of each fragment are labeled with a chain terminator, and this allows the determination of the DNA sequence.…

Next Generation Sequencing Could Dramatically Impact Life Expectancy

Introduction A Centers for Disease Control website provides a definition for life expectancy as “the average number of years that a hypothetical group of infants would live at each attained age if the group was subject, throughout its lifetime, to the age-specific death rates prevailing for the actual population in a given year” (1). It is essentially the time a person or other organism is expected to live based on…

HLA and Pharmacogenetics

Introduction For years, the unpredictability of drug reactions has served as an underlying uncertainty in the safety of medications. This is because many of these reactions are specific to certain individuals and populations and under specific circumstances with an unknown basis. Adverse drug reactions can be very medically devastating, leading to severe consequences including death. The capacity to find a means to predict the risk of adverse reactions for patients…

DNA Sequencing: The Backbone of Personalized Medicine

Concept of Personalized Medical Care As a society, we have been accustomed to the concept of a “one-size-fits-all” approach to healthcare. However, this has not been ideal for many people and limits the success of medical management. There are instances where there is some level of tailoring to the individual, but not to the extent needed to address the numerous nuisances that can affect the optimal results of a person’s…

NGS DNA Sequencing

Next-Generation Sequencing Revolutionizes Drug Discovery and Development

Next-Generation Sequencing (NGS) Overview Next-generation sequencing is a massive parallel sequencing technology. Genomic DNA is extracted, fragmented, and linked to adapters and primers for the amplification reaction (PCR) to generate a library. DNA fragments in the library are simultaneously sequenced. This provides a massive set of sequence data in a matter of days. The data obtained is processed with bioinformatics software and interpreted. In addition to rapidly obtaining sequence data…
