DNA Lab Report SungYong Jang What is DNA? What do the letters stand for? What is it composed of? Where is it found? What is it shaped like? Answer in full sentences. It is the genetic material that can be passed on from parent to offspring DNA --> Deoxyribonucleic acid
It composed of Deoxyribose (5 carbon sugar), a phosphate and a Nitrogonous base (the 4 N-bases are Guanine, Cytosine, Adenine and Thymine) It is a double helix (looks like a twisted ladder.)
DNA is found in the nucleus of most cells

Visit the above website, read a scientist’s biography, watch an interview, or work through an experiment to identify scientists, dates, events, and facts that makeup the major advances (so far) in the science of DNA. List the answer in front of each question below: 1. Johann Gregor Mendel__________It took him eight years and more than 10,000 pea plants to discover the laws of inheritance. 2. ___ Linus Pauling_______Even though he added an extra strand to the structure of DNA, he ultimately won two Nobel Prizes: the Nobel Prize in Chemistry and the Nobel Peace Prize. 3. _____ Martha Chase and Alfred Hershey These two scientists used a common kitchen appliance to help show that phage DNA carries instructions to make new viruses. 4. ____ Barbara McClintock______Next time you’re munching away at the movies, think of this Nobel-Prize winning scientist who figured out the process of transposition in corn chromosomes. 5. _____ 1962_____When did Watson, Crick, and Wilkins win the Nobel Prize in Physiology or Medicine for their model of the structure of DNA? 6. _____ David Baltimore_____This scientist found that some viruses have an RNA-dependent DNA polymerase that was later named “reverse transcriptase.” He was one of three who shared in the 1975 Nobel Prize in Physiology or Medicine. 7. _____ The Human Genome Project_____J. Craig Venter’s company, Celera Genomics, worked on...
