1. DNA & Genetic Information

Key Concepts & Definitions

  • DNA (Deoxyribonucleic Acid): The molecule that carries genetic information in all living organisms, composed of two strands forming a double helix.
  • Genetic Material: The hereditary information encoded in DNA that is transmitted from parent to offspring.
  • Chromatin: The complex of DNA and proteins (mainly histones) in the nucleus, which condenses to form chromosomes during cell division.
  • Chromosome: A highly condensed structure of DNA and proteins, visible during cell division, carrying genetic information.
  • Gene: A segment of DNA that codes for a specific protein or functional RNA, serving as a unit of heredity.
  • Replication: The process of copying DNA prior to cell division, ensuring each daughter cell inherits a complete set of genetic information.
