Gergor Mendel
He cross pollinated yellow round pea plants with green wrinkly peas. They were all yellow and round, like the dominant yellow pea plants. He tested and experimented on over 29,000 peas. So he realized that they must have had DNA that lined up or followed a certain pattern for all of them to be the yellow peas. Therefore, that was probably true for most living things. -
Fredrich Meischer
Know for discovering nucleic acid (DNA) -
Fredrick Griffith
Saw that DNA is a molecule of inheritance. -
Erwin Chargaff
Chargaff was the scientist that took samples from different types of DNA and found out that the thymine was almost euqual to the adienine. Also the amount of guanine was almost the same amount of cytosine. This became known as Chargaff's Rule. -
Oswald Theodore Avery
This scientist figured out that DNA is the material in which the genses or (gentetic information) and chromosomes are made. -
Maurice Wilkins
he figured out the structure fit DNA. -
Hersey and Chase
They proved that the DNA, contains the phage genes. -
Rosailind Franklin
she worked on the X-ray diffraction images of DNA. -
Fredrick Sanger
proved that genes or genetics are carried out by chromosomes. -
John Sulston
They were awarded for the work they had done in understanding the development and dividing of the cells in C. elegans. -
Thomas Hunt Morgan
Established the chromosonal theory of inheritence.
