Key Concepts & Definitions

  • DNA (Deoxyribonucleic Acid): The hereditary material in all living organisms, composed of two strands forming a double helix that encodes genetic information.
  • Nucleotide: The basic unit of DNA, consisting of a phosphate group, a deoxyribose sugar, and a nitrogenous base.
  • Double Helix: The spiral structure of DNA, formed by two complementary strands twisted around each other.
  • Complementary Base Pairing: The specific pairing of nitrogenous bases—adenine (A) with thymine (T), and cytosine (C) with guanine (G)—held together by hydrogen bonds.
  • Antiparallel Strands: The two DNA strands run in opposite directions, one 5' to 3' and the other 3' to 5', facilitating replication and transcription.
  • Base Pairing Rules: The principle that A pairs with T via two hydrogen bonds, and C pairs with G via three hydrogen bonds, ensuring accurate copying of genetic information.
