Key Concepts & Definitions

  • Deoxyribonucleic acid : Deoxyribonucleic acid is a nucleic acid that carries genetic code and is located in the nucleus of cells.
  • Nucleotide : A nucleotide is a DNA subunit made of deoxyribose sugar, a phosphate group, and a nitrogenous base.
  • Chargaff’s rule : Chargaff’s rule states that in DNA adenine pairs with thymine and cytosine pairs with guanine.
  • DNA double helix : A DNA double helix is a double-stranded, helical structure where the strands are twisted around each other.
  • Hydrogen bonding : Hydrogen bonding is the attraction between DNA bases that holds complementary pairs together.
