There are four building blocks of DNA called nucleotides (As, Ts, Cs, and Gs); the method of determining their natural order is known as DNA sequencing. The study of the order of nucleotides will inform the scientists more about the genetic information that a DNA strand carries. If the scientists are successful in this mission it will enable them to remove a particular trait from the DNA or to add a trait. For example if a disease is hereditary in a family then the child will most likely suffer from the same disease that the parent carries, but with DNA sequencing the particular disease could be removed from the DNA chain and the child would grow up free of the disease.
Market for DNA Sequencing
DNA sequencing particularly the next-generation sequencing (NGS) has grown into a practice of essential life science subject for researches on the genetic level. The global market for DNA sequencing was evaluated at USD 6.6 billion in 2016 and is expected to reach USD 9 billion by 2020. The market driving factor for this technology is the research for curing cancer, apart from that infectious disease and reproductive health are also fuelling the market. It is due to these factors that the global market for DNA sequencing is expected to grow at a CAGR of 18.7% for the next 5 years.
Currently North America holds the largest share in the international market but the Asia Pacific region would soon leave it behind due to the increasing demand for personalized medicine and rising awareness among the people.
