Deep Insights on the Isolation of DNA

While you are well familiar with the term ‘DNA’ the isolation of DNA may seem a bit bewildering at first. The theory and know-how are a crucial part of the Life Science subject. A broad understanding of life processes at the molecular and cellular levels can give you a deep comprehension of the DNA structure. If that’s already holding your attention, studying the thesis from scratch is the correct thing to do. How about sparing a few minutes and getting your basics right? Begin by spending a moment or two on these blogs.


What is Life Science?

Career in Life Sciences – Scope & Jobs

Before we get into the isolation of DNA and its extraction process, here are two foremost factors.


First, DNA (Deoxyribonucleic Acid) is a unit of living or once-living organisms.

Second, DNA can be extracted and examined.

What is DNA isolation?

DNA isolation is the first crucial step in swotting a particular DNA chain. An intricate DNA population and genome structure are broken down with the help of this essential technique. In a snippet, the process involves separating a component from the cortex and then purifying the nucleic acid. Interestingly, the crude measure has various sources. As mentioned above, the process of DNA isolation can be done on any organism, including hair, blood, nails, sperm, bloodstains, urine, saliva, bones, nails and more.


The process and the purpose for the isolation of DNA vary. The technique used to isolate DNA will be conditioned on several factors such as the sample size, age and source. However, despite the difference in approach, the process of isolation remains the same. Biotechnology adopts the procedure to diagnose the pressing problems of today revolving around life-threatening diseases like cancer in the medicinal field. Scientists are major DNA hunters to recognize different species and understand how they are controlled.

Speaking of forensic science, experts conduct DNA isolation to identify individuals in case of any unpleasant circumstances of robbery, rape, war or accident. Currently, DNA isolation is a routine procedure in the mentioned spheres. Did you know when the first DNA isolation was conducted? Swiss Biologist and Physician, Johannes Friedrich Miescher, was the first to isolate nucleic acid in 1869.
