Erica Phillips'. Hour 2. Genetics

  • Gregor Mendel

    Notices traits in pea pants and tests them. Never used to identify DNA
  • Friederick Meishcher

    Isolated DNA. Never thought it to be genetic material
  • Walther Flemming

    was the first to detail the chromosomal movements in the process of mitosis.
  • William Bateson and Reginald Punnett

    They experimented with two characteristics in sweet peas, flower color and pollen shape, and discovered inheritance patterns that were totally inconsistant with Mendelian principles
  • Thomas Hunt Morgan

    Found out what cross over is
  • Frederick Griffith

    "Transforming Principal". Knew something was transferred from one cell to another
  • George Beadle and Edward Tatum

    They experimented by growing orange bread mold and examined strains that wouldn't grow on the usual simple growth medium.
  • Oswald Avery

    Oswald Avery discovered that DNA is the material of which genes and chromosomes are made.
  • Oswald Avery

    With Colin Macleod and Maclyn Mcarthy found that DNA was the trasforming principal
  • Rosalind Franklin

    Hired to improve X-ray crystallography
  • Maurice Wilkins

    Found the double helix
  • Alfred Hershey

    With Martha Chase confirmed DNA was the trasforming factor. Radioactive labaling.
  • Alfred Hershey and Martha Chase

    They infected E-Coli with T2 phage and labeled it with radioactive material so he could tell what was being infected, and proved that genetic material infects and isn't a protein.
  • James Watson and Francis Crick

    Used Maurice ad Rosalind's ideas and made a model of the double helix. They are credited with the discover.
  • Erwin Chargaff

    Chargaff's Rule. Determine how the bases are pared. A pairs with T. C pairs with G
  • Frederick Sanger

    He is known for the sequence of insulin by amino acids
  • Frederick Sanger

    He is known for the sequence of insulin by amino acids
  • Linus Pauling

    Pauling developed the theory of the molecular clock, which enables one to judge the separation in time between two species
  • Marshall Nirenberg

    cracks the genetic code
  • ROY BRITTEN

    Roy britten and David Kohone found that mouse cells contain multiple copies of very similar dna sequences.
  • Gene Theraphy first used

  • Thomas Hunt Morgan

    He proved that genes or genetic material is carried on chromosomes by his experiments with fruit flies
  • John Sulston

    Played a large role in the human genome project
