STORY BOARD DNA DISCOVERY
Text z Príbehu
- IN 1881
- I think that characteristics might pass from generation to generation.
- Before all discoveries and findings, Gregor Mendel which is known as the "Father of Genetics" suggested that characteristics are passed down from generation to generation
- ALL STARTED IN 1869, WHEN FRIEDRICH MIESCHER IDENTIFIED "NUCLEIN" INSIDE OF HUMAN WHITE BLOOD CELLS BY ISOLATING A MOLECULE THAT WOULD LATER BECOME KNOWN AS DNA.
- Im going to isolate a molecule from a cell nucleus
- What is this thing I have discovered?!I am going to name it "Nuclein"
- In 1881, Albrecht Kossel won the Nobel Prize for finding the basic building blocks of DNA: adenine (A), cytosine (C), guanine (G), and thymine (T)
- Nobel Prize is for...Albrecht Kossel
- NOBLE PRIZE WINNERto: Albrecht Kossel
- Thank you all of you!
- So, we know the basic building blocks of the DNA. Our goal is discover the structure of the DNA
- THE STRUCTURE...
- In 1944, Oswald Avery, Colin MacLeod and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes.
- This principle is going to be revolutionary!
- This shows that DNA, not properties, transform cell properties!
