DNA Sequencing: Changing the Landscape of Science and Biology


DNA sequencing is becoming increasingly popular in medicine today. The advancements in technology have allowed for scientific advancements which have helped to change the ways in which individuals are diagnosed and treated. With its abilities to predict and target certain diseases and bodily issues, it is understandable why so many individuals are taking interest in this innovative process. As such, there are a few things and characteristics of the sequencing that you should be aware of.

What is DNA Sequencing?


The process of DNA sequencing can be simply described as determining the precise order of a person’s genes. DNA is comprised of four particular molecules:


  • Adenine
  • Cystosine
  • Guanine
  • Thymine



These molecules intertwine with one another to produce unique combinations and gene patterns that are unique to each individual, yet still quite similar. As such, it allows for certain processes and evaluations to be generalized, which has contributed to the advancements that have been allowed through sequencing research. For instance, though certain individuals may require different types of treatments, scientists can identify particular strands of DNA that help to identify the illness that the individuals have.


What Methods are Used?


There is one particular method that is generally used in sequencing. Basically a DNA sample is drawn and is then analyzed. The process has been explored for several years. According to the National Human Genome Research Institute, it has been researched since the mid 1970’s. Over the years scientists have not only been able to dissect the human DNA sequence, but they have also been able to analyze the sequences of other species, which has contributed to other scientific discoveries. Some of the main species include:


  • Mice and Rats
  • Fruit Flies
  • Dogs
  • Chicken


They have even been able to extract DNA sequences from a few plants as well. As with the human body, such knowledge has helped to advance understanding of the function various species and how it relates to humans.


What are its Uses?


Each individual’s particular sequence can help to determine how well their body will take to specific treatments. A popular use now is for cancer patients; examining an individual’s sequence helps doctors predict how a patient’s body will react to certain treatments. This allows them to create tailored plans for the patients and hopefully gain the most effective results. The sequencing can also be used to predict different diseases in babies, which allows for proper treatment as soon as possible. This has been used to enhance or save the lives of many children. With the continued advancements of sequencing it is thought that in the future sequencing may be completed in all or most individuals, so that doctors may use each patient’s personal sequence to help treat or diagnose them.


DNA sequencing has many beneficial uses and has helped to advance the treatment and prevention of several different diseases. As such it has become a popular testing method for locating and developing treatment for terminal diseases, amongst other processes. It is also being explored as a method of locating diseases within children to aid in treatment at a young age.
