Welcome to this informative article on DNA. Let’s see what is DNA?

  • DNA stands for deoxyribonucleic acid, and it is a long, spiral-shaped molecule that carries genetic information.
What is DNA
  • It is found in the nucleus of most living cells and is made up of two strands of nucleotides that are twisted together to form a double helix.
  • The order of the nucleotides in DNA determines the genetic information that is transferred from one generation to the next.
  • The structure of DNA was first described by James Watson and Francis Crick in 1953, based on the work of Rosalind Franklin and Maurice Wilkins.
  • It is composed of four nucleotide bases: adenine (A), cytosine (C), guanine (G), and thymine (T). The genetic information stored in DNA is determined by the sequence of these bases.
  • The human genome, which is a complete set of genetic information in a person’s DNA, contains approximately 3 billion base pairs.
  • It is constantly repairing itself and replicating itself so as to maintain the integrity of the genetic information it contains.
  • It can be found not only in the cells of living organisms but also in some viruses and in ancient fossils.
  • Scientists are able to study DNA to learn about a person’s ancestry, diagnose genetic disorders, and develop new treatments for diseases.
  • There are many different techniques and technologies that are used to study DNA, including sequencing, microarrays, and polymerase chain reaction (PCR).
