What is DNA made of?DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.The four types of nitrogen bases found in nucleotides are: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown.The complete DNA genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.
What ‘s DNA database?A DNA database is computer-based system that contains biological information “Big Data”whichregulatedandmaintainedbythegovernment, or controlled by private entity. This technology is a must-have tool to facilitate the state’s machineries like Police,Immigration,Forensic, Heath CareandSecurity.
In 1990 scientists started the Human Genome Project (HGP), that comprises vast of international projects aiming to decode all human genetic information. The main reason behind this monumental studies is to enable scientists understanding the primordial code of humans’ fabric and read its “instruction manual”. A rough draft was completed in June 2000. This was a huge milestone in understanding how our genes determine who really we are. Since all therapeutics are rooted from the information produced by the Human Genome Project, then time will tell after the decoding completion.
