What is DNA?

  • Deoxyribose Nucleic Acid (DNA) is the genetic material in most organisms that carry coded genetic information in the form of base pairs, arranged in a linear sequence and represented by the letters A (Adenine), G (Guanine), T (Thymine) and Cytosine (C).
  • A single DNA molecule will contain millions of these base pairs and arrangement of these on the strand results in the formation of a genetic code that contains information regarding every trait of the organism.
  • This DNA is transmitted from the parent to the offspring. Sometimes, genetic disorders which arise due to a faulty or defective gene are also transmitted to the offspring.
