a) DNA full form is deoxyribonucleic acid. It is a long molecule and contains a person's unique genetic code. It holds instructions for making all the proteins in our bodies. DNA contains four basic building blocks. They are called adenine, cytosine, guanine, and thymine.
b) The DNA test is performed by collecting buccal cells found on the inside of a person's cheek using a buccal or cheek swab. These swabs are made of wooden or plastic stick handles and will have cotton on the synthetic tip. The Sample collector rubs the inside of a person's cheek to collect as many buccal cells as possible, which are then sent to a laboratory for testing.
c) If you want to do a paternity test, you can do the DNA collection yourself using a home kit. But the results obtained from this sample are not legally valid. If the results are to be legally valid the test must be done by a lab
The DNA sample collection should be witnessed by an impartial third-party at an approved facility.
The following are the approved places for the collection of the sample.
An AABB-accredited DNA laboratory location
Mobile provider or brick-and-mortar collection facility approved by the lab
In the Hospital or in the court. It can be done in a doctor's clinic or Lawyer's office also.
d) The DNA testing lab at Hyderabad:
DNA labs India
301 3rd Floor GS Towers
Himayat Nagar, Hyderabad – 500029
e) The cost of DNA testing will be around Rs.20000/-
f) adenine (A), guanine (G), cytosine (C) and thymine (T). These four chemicals are the basis of DNA. A and T will pair up. Similarly, G and C will pair up. These pairs will link to a phosphate molecule and a sugar molecule. This structure is known as a nucleotide.
DNA sequencing will be unique in human beings. No two people will share the same DNA.
