Genomic DNA (gDNA) is found in the chromosomes and has a higher molecular weight and is longer as compared to plasmid DNA. This is what scientists need and collect when doing genome sequencing.

One purpose of genome sequencing is to help scientists understand how the genome works, and how genes work together to enable growth, development, and maintenance of the entire human body or any other organism. In order for a scientist to be able to study how the genome works, a process by the name genomic DNA extraction has to take place. There are several ways to extract the genomic DNA and from different sources including blood, hair, urine, etc.

Did you know that it’s possible to successfully extract DNA/RNA from dried blood spots even after 10 years? There is enough data to support this assertion. However, the best output can be achieved if storage is done at room temperature using dried samples. As technology evolves, microsampling has emerged as a crucial concept in medicine and healthcare alongside other groundbreaking innovations, representing the next generation of dried blood spot (DBS) technology.

As our international and interpersonal networks grow larger and stronger, a little information can go a long way. Our world is getting smaller. Our technology is getting smaller, too. And it's getting a lot more powerful.

Collecting, storing, and analyzing DNA is a vital part of many medical fields and disciplines. To achieve viable results, regardless of the discipline, there is a need for high-quality and stable samples from which DNA can be extracted. Fresh blood samples are not always viable due to difficulties in collection, transportation, or storage. However, viable and stable DNA samples can also be extracted from dried blood.

Early diagnosis improves care management, provides better outcomes, and allows for more cost-effective treatment. While early diagnosis may not always be easy to achieve, recent studies suggest that rapid whole-genome sequencing may hold many answers, and pose new and useful questions.

Recent technological advancements in the realm of gene editing will give humanity the power to manipulate the very stuff of life.
