DNA timeline

  • Gregor Mendel

    Gregor Mendel
    He discovered the laws of inheritance. Law of segregation- "A gene pair defines each inherited trait" Law of dominance- Genes will show the dominant trait inherited. This was interesting because he did his experiments on pea plants
  • Friedrich Miescher

    Friedrich Miescher
    He isolated nuclei, He was also the first to identify that DNA was a distinct molecule. This was interesting to me because all of his study started out with trying to find out why he has a hearing disability
  • Barbara Mcclintock

    Barbara Mcclintock
    She specialized in cytogenetics which is the study of inheritance and function of chromosomes. This was interesting to me because she did her studies on corn because the corn would be a controlled experiment.
  • Oswald Avery

    Oswald Avery
    History- He reported that DNA is the substance that causes bacteria transformation. Interesting Because he used purified DNA.
  • Erwin chargaff

    Erwin chargaff
    History- Figured out that genes were made of dna. Interesting- Because it helped two other scientist in their discovery of dna structure.
  • Rosalind Franklin

    Rosalind Franklin
    History- Worked on x-ray diffraction images of DNA Interesting- Even though she knew it was difficult to have a career and become a scientist for women she still tried.
  • Hershey- Chase

    Hershey- Chase
    They confirmed DNA was a genetic material.This was interesting to me because they did this experiment on a virus.
  • Francis Crick

    Francis Crick
    He was responsible for Figuring out the double- helix structure of DNA. I found this interesting Because he got inspire by reading a book.
  • James Watson

    James Watson
    He was the co-discoverer of the structure of DNA. Interesting- Because he went from bird watching to wanting to learn about genetics and DNA
  • Marshall Warren Nierenberg

    Marshall Warren Nierenberg
    He cracked the genetic code along with Gobind Khorana and Robert Holley. This was interesting to me because he started out as a doctor.
