8. DNA HISTORY An experiment in 1928 by Frederick Griffith: He removed DNA from one type of bacteria & put it into a 2 nd type of bacteria. The 2 nd bacteria took on the characteristics of the 1 st bacteria.

9. QUESTION # 1 WHAT DID GRIFFITH’S EXPERIMENT INDICATE ABOUT DNA?

10. AND THE ANSWER IS…. DNA CARRIES THE GENETIC INFORMATION THAT DICTATES AN ORGANISMS CHARACTERISTICS. Page 31

11. THE STRUCTURE OF DNA In 1953, James Watson and Francis Crick were accredited to discovering the structure of DNA. Watson, Crick, and Maurice Wilkins were awarded the Nobel Prize for Physiology and Medicine in 1962. But should they have received the credit??? Page 31

12. Rosalind Franklin Franklin refined the technique of X-ray crystallography to study DNA and produced the famous photo 51. From photo 51 she determined that DNA had to be a double helix. Her partner, Maurice Wilkins, shared photo 51 with Watson & Crick, who published the results before Franklin. Franklin died in 1958. http://www.youtube.com/watch?v=JiME-W58KpU

13. DNA is wound up in tight chromosomes which are located in the nucleus Its shape is a twisted double helix

14. DNA is genetic material that carries information about an organism and is passed from parent to offspring. (Blueprint of life) Found in the nucleus of cells. Tightly coiled DNA makes chromatin & chromatin makes chromosomes.

15. Every organism’s DNA is different except clones & identical twins. DNA contains the genetic code of the organism - the instructions that tell the cell and the whole living thing what proteins to produce. The proteins that a cell makes control what that cell does - the cell's function. This code is based on the code from that organism's parents.

17. DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating. The structure of DNA is a twisted double helix (twisted ladder).

18. Adenine always pairs with Thymine A-T or T-A Cytosine always pairs with Guanine G-C or C- G

19. Nitrogen Bases There are two kinds of nitrogen- containing bases - purines and pyrimidines. Purines: Adenine and Guanine Purines are the larger of the two types of bases found in DNA Pyrimidines: Cytosine and Thymine Adenine and guanine are found in both DNA and RNA
