DNA is a biological molecule which is responsible for the development and functioning of each unique living thing in the world. It encodes the physical and biological processes of all microorganisms. Quite simply, it’s the formula of life. That means it is a natural measure of identity preservation provided by nature, and it is a unique thing in every human, and according to DNA code we are able to identify any person.

Let’s see into some exciting facts about DNA.

Medical Facts about DNA

  • DNA includes a dual helical framework, like a twisted ladder. The particular steps of this ladder are constructed with the nucleotide base pairs while the sides are comprised of deoxyribose sugar associated with each other together with phosphodiester ties.
  • In nature, most DNA has a negative supercoiling because of the existence of enzymes called topoisomerases.
  • Experiments performed by Alfred Hershey as well as Martha Chase in 1952 served to prove that DNA is the individual genetic substance in microorganisms.
  • Its chemical substance framework was found by James Watson and Francis Crick in 1953, in accordance with the fresh details of Rosalind Franklin as well as Maurice Wilkins.
  • The 1958 research by Matthew Meselson and also Franklin Stahl served to confirm that the method of DNA replication was semi-conservative.
  • The dual helical strings are 20-26 Å in width, and the distance between two nucleotide units in human DNA is actually4 Å. The helical structure has major and minor grooves that are different in size and therefore distance between strands is uneven.
  • This molecule has three possible forms, or conformations: B form, Z form, and A form. The A and B versions are dual helices that run in a right-hand direction of the spiral. The Z conformation of DNA molecule has a helical structure that turns in a left-hand direction.
  • The B form and chemical framework can be found in the genome of most microorganisms.

Interesting Facts about DNA

  • DNA can certainly be separated from some biological materials, such as dead skin cells, follicles of hair, bloodstream, perspiration, pee, saliva, and so forth.
  • Commonalities in hereditary codes between similar people help set up family history and genealogical charts.
  • Scientists claim that the whole human genome would certainly take up a space of 200 gigabytes on any computer hard drive.
  • If you were to constantly read all the bases of the individual genome, with zero breaks or cracks in between, it could last 52 years. Although writing it for 7 hours per day at the velocity of 58 words for each minute, will need 55 years to write each character completely.
  • At least to some degree, it is possible to test your DNA and see what it says about you. Some examples of market-ready test kits can be found on the Best DNA Test Kit portal.
  • The first sequenced individual genome was released on the 50th anniversary of the discovery of the double helix structure of DNA molecule by Watson and Crick.
  • Scientists say people have 1-4% prehistoric genes, while we possess a 94%-98% hereditary similarity to our nearest ‘cousins’ chimpanzees.
  • Family genes constitute just 3-5% of the whole genome of a living being.
  • The International Space Station carries copies of the genome of renowned and valuable individuals like Lance Armstrong and Stephen Hawking onboard, to be capable of reviving civilization in the event of apocalyptic devastation of the world. This large memory device is called Immortality Drive.
