The History of D.N.A

By Orel
  • Gregor Mendel

    Gregor Mendel
    He goes by many names, the "Founder", the "Father", or the scientist who studied pea plants. He discovered the fundamental laws of inheritance by studying the inheritance traits of pea plants. He studied the traits of a total of 29,000 pea plants.
  • Friedrich Miesher

    Friedrich Miesher
    He discovered the nucleic acid aka DNA or deoxyribonucleic acid.He made this discovery in the year, 1869, and 2 years later he told the world about it in the year 1871.
  • Thomas Hunt Morgan

    Thomas Hunt Morgan
    He discovered the chromosomal theory of inheritance by studying genetics and heredity his whole college career. He recieved a nobel prize for his discovery.
  • Hermann Joseph Muller

    Hermann Joseph Muller
    He found out that x-rays could have a mutation effect against DNA. In the year 1920, he won a nobel prize for discovering that x-rays can DEFINETLY cause mutation in the DNA.
  • Barbara McClintock

    Barbara McClintock
    Barbara is one of the most distinguished cytogeneticists. She discovered the translocations, inversions, deletions and ring chromosomes in corn by experimenting with the effect of the x-ray on corn chromosomes.
  • The genetics of fruit flies

    The genetics of fruit flies
    Thomas Morgan discovered that fruit flies (males and females) had different eye color at some times of the year. He later discovered that each sex of the fruit fly have different eye color during the seasons.
  • Marshall Warren Nirenburg

    Marshall Warren Nirenburg
    He is the scientist who broke the Genetic code and was awarded a nobel piece prize with the help of a scientist named Har Khorana.
  • James Dewey Watson

    James Dewey Watson
    Watson has played a role in the development of science policy, from the War on Cancer, he thought that the key of understanding life was solving the structure of DNA.
  • Conjugating Bacteria

    Conjugating Bacteria
    Scientists, Joshua Lederburg, and Edward Tatum found out that the ability of DNA is the transfer of genetic material between bacterial cells by direct contact.
  • The true look of DNA

    The true look of DNA
    Dr James Watson, Professor Francis Crick, Dr Rosalind Franklin, and Professor Maurice Wilkins, discovered the double helix structure of DNA, which is the true image of the deoxyribonucleic acid.
  • Francis Harry Crick

    Francis Harry Crick
    A co-discoverer of the structure of the DNA molecule and an important theoretical molecular biologist who revealed the genetic code.
  • Triple-stranded Helix

    Triple-stranded Helix
    Scientist Pauling told the world the triple-stranded helix. hypothesis. He said it looks the same as a regular DNA strand but has three oligonucleotides wind around each other and form a triple helix. But others said no such thing can exist.
  • The Watson and Crick double helix

    The Watson and Crick double helix
    Scientist Watson and Crick were interested in finding out the structure of DNA, later on, they published the first accurate picture of the DNA molecule.
  • The Genetic Code

    The Genetic Code
    Scientist Marshall Nirenburg and Har Khorana, cracked the genetic code with their cooperation..They successeded by matching amino acids to synthetic triplet nucleotides.
  • The changes

    The changes
    Barbara McClintock discovered that genes are able to change position on chromosomes like a normal person would change old clothes for example.
