WHAT IS DNA ?
Deoxyribonucleic Acid (DNA) is served as our genetics instruction and consisted of all the necessary information to build a fully functional human being, living organisms and virus.
DNA contains two strands wrapped around each other in a helix (known as the double helix). Each nucleotide includes 3 parts: a phosphate group, a sugar molecule and one of 4 bases Adenine, Cytosine, Guanine or Thymine. The backbone of DNA is based on a repeated pattern of a sugar group and a phosphate group. These strands are held in place by one of the four chemicals called bases:
Human being DNA has at least 3,000,000,000 (3 billion) nucleotides in sequence. The sequence of nucleotides in DNA and RNA that serve as instruction manual for synthesizing proteins through the process of transcription and translation.
Most part of the DNA is more or less in everyone but there are different in various part of the DNA that makes everyone of us unique. Due to this special feature, DNA can be used to identify individuals.
At DNA Laboratory, we based on this scientific fact that half of a person's DNA inherited from their father and half from their mother to test for possible relationships between people and establish a family connection. DNA can also establish relationships between more distant relatives, too.
DNA relationship technology innovation, process automation, databases, computer analysis power and good laboratory practices are essential to the pursuit of DNA human identification and confirmation of the biological relationship. One of the very important inventions is the Polymerase chain reaction (PCR) technique.
Our PCR based DNA relationship tests (DNA test) produce conclusive results to prove parentage (Biological parents) with power of inclusion can be up a maximum of 99.99% or more and exclusion of 100%. Now, DNA laboratory scientists can even perform the test on pregnant mother blood that contains a tiny amount of the fetus DNA to determine parentage relationship before the child is born.
