📖 1. DNA, chromosomes and genes

🔑 Key Concepts & Definitions

  • DNA : DNA is the chemical molecule that carries hereditary information inside cells.
  • Chromosomes : Chromosomes are rod-like structures in the nucleus made of tightly packed DNA.
  • Genes : Genes are specific DNA segments that contain instructions for inherited traits.
  • Condensation of DNA : DNA condenses to form chromosomes inside the cell nucleus.

📝 Essential Points

  • Chromosomes are formed by condensed DNA inside the cell nucleus.
  • Chromosomes contain information such as sex, species, and some diseases.
  • Genes are located at precise positions on chromosomes.
  • Genes determine inherited characteristics like traits of the individual.

💡 Memory Hook

DNA condenses into chromosomes; chromosomes carry genes; genes “write” traits.
