  2. Smooth Heated Smooth Rough Bacteria Evidence Smooth Smooth bacteria cause mouse die Rough Rough bacteria no change Heated Smooth Heat to 60oC bacteria died

  3. Heated Smooth Rough Rough Heated Smooth Heated Smooth Heated smooth bacteria mixed with rough can cause mouse dead Rough Some things transmit to rough. Transforming Principle

  4. Life cycle of Bacteriophage VIRUS

  5. ANIMATION

  6. DNA Structure

  7. Phosphate base Ribose Adenine Cytosine Guanine Thymine Nucleic Acids Purine Pyrimidine

  8. Nucleic Acid

  9. ATGC combination

  10. DNA Replication During cell division, DNA must reproduce itself, so that all genetic information can be transferred to daughter cells. There are three hypothesis about DNA replication.

  11. Experiment Semiconservative Replication

  12. Replication mechanism ANIMATION

  13. Gene concept Gene is a sequence of DNA. Each chromosome contains a lot of gene. Each gene control a characteristic. So each chromosome may control a lot of gene.

  14. Transcription How do gene control characteristic? Gene is a sequence of DNA which contain genetic information. A messenger transports the information out the nucleus. The messenger is read by ribosome and transform to protein as building block of our body. The messenger is messenger RNA.

  15. ANIMATION

  16. How do mRNA work?

  17. Translation

  18. tRNA

  19. Translation

  20. Translation ANIMATION

  22. Whole Process

  23. Use of DNA technology Funny Website
