DNA microarrays are used in molecular biology to perform numerous genetic tests at the same time. By allowing parallel processing, the microarray greatly reduces the amount of time required to study new theories or biotech phenomena. The array itself is made up of a series of microscopic spots of DNA oligonucleotides possessing a specific DNA sequence. The spots are referred to as features while the sequences are known as probes. The degree of acceleration is basically determined by the number of probes.
A probe is attached to a silicon chip with a covalent bond from a chemical like an epoxy-like substance. Microscopic beads can also be used. A DNA array is basically the same as other microarrays. It just uses DNA as its detection mechanism. Just like a standard microarray, a DNA array can also suffer from a inaccuracies, in-efficiencies, and production delays from the fabricator.
Take a close look at the genetic and chemical nature of depression and you will get a better understanding of how 121 million people can be clinically depressed.
The Significance of Biobanking
The value and importance of biobanking is increasing each day and slowly people are getting acquainted with it. However, the question that might taunt many is that what a biobank is and to put it in simple terms, a biobank is a place where biological samples (especially of humans) are preserved and stored. The stored samples of a biobank are meant for data analysis and are usually a research hub.
