Y-represents hydrogen bond


  • DNA is a type of nucleic acid, that carries genetic information in organisms. DNA is made up of nucleotide bases; guanine, Cytosine, Adenine,l and Thymine, which are the building blocks of nucleic acids.
  • Complementary base pairs of guanine with cytosine and adenine with Thymine between the DNA strands connect to each other using hydrogen bonds.
  • Hydrogen bonds between the complementary nucleotides keeps the two strands of DNA helix together.
