The Germ Theory of Disease is published
The germ theory of disease states that variable of disease are caused by microorganisms discovered by Louis Pasteur. Little living organism that one only can be seen with magnification. It affects to animals, human and other living things. https://en.wikipedia.org/wiki/Germ_theory_of_disease -
The Origin of species by means of Natural Selection is published
Charles Darwin wrote the book " The origins species" published on 24 November 1859. Two main points of Darwins theory is that diverse groups of creatures involve jumping from one or common ancestors. Suggested a mechanism for evolution located at natural selection. -
Hamarck develops Hypothesis of evolution by means of acquired chacteristerstics
In 1859, Hamarck published acquired charcteristics of inheritance of his theory. He observed that the fossils in a sequence had grown closer to living species. He declared that the if an organism happens to change than will be passed on to its offspring. -
The Voyage Of the HMS Beagle
In 1859, Charles Darwin published his book " The Voyage of the Beagle". Darwin took a five year journey when at first it was two with the captain and crew of the HMS Beagle. The journey was taken from south America and all around the world , December 1831 to October 1836.

Louis Pasteaur refutes spontaneous generation
In 1864, Louis Pastear hypothesis was that if cells lifts from nonliving spontaneous and if thinks they should show up in sterile broth. Pasteur made an experiment to test whether sterile nutrient could spontaneously genotype microbial life.https://amoebamike.wordpress.com/2009/10/06/spontaneous-generation-a-brief-history-of-disproving-it/ -
Gregor Mendel publishes works on inheritance of traits in pea plants
In 1865, Gregor Mendel published his results from one of his genetics experiment with the pea plants. From his experiment he discovered the fundamental laws of inheritance. http://www.dnaftb.org/1/bio.html -
Neils Bohr develops the Bohr
In 1913, Neil Bohr discovered of the nucleus and development of an atomic model. The atomic model is described with small atoms in the nucleus and with positive charge surrounded by electrons. https://www.livescience.com/32016-niels-bohr-atomic-theory.html -
The Innocence project is found
In 1922, Peter Neufield and Barry Sheck helped people who was mistakenly blamed from a crime. The project uses DNA testing to correct people or to make sure who have been wrongly convicted of crime.

Frederick Griffith describes the process of transformation
In 1928, Frederick Griffith was famous for his experiment of how the bacteria can distinctly change their function and form. Because Griffith discovery it has helped many scientists such as int the medical community discover to make more efficient antibiotics.

Avery, MacLoed and McCarty determine that DNA is the molecule that carries the genetic code
The 3 Canadian and American researchers Oswald Avery, Maclyn, McCarty and Colin Macleod. Responsible of for the identification of the transforming principal. The experiment was concluded that the transformation principal is the DNA , after destroying the DNA in the solution by using R bacteria and no transformation occurred.https://www.yourgenome.org/stories/revealing-dna-as-the-molecule-of-life -
Hershey-Chase experiments are published
Hershey Chase made an experiment in 1952. With the help of his research assistant Martha Chase, They proved to everyone how DNA was the genetic material. The location where they did their experiments " Cold Spring Laboratory" demostrates that the DNA, of the phase or bacteriophage for short, a type of virus living organism in a bacteria.

Roselind Franklin works with DNA and crystallography and develops "image 51"
Franklin took the photo 51 or x- ray diffraction image of crystallized that was shaped of a helical form of the molecule. She was instrumental in discovery the molecular structure of DNA.http://www.dnaftb.org/19/bio-3.html -
Watson and crick purpose the double helix model of DNA structure
In 1953, Watson and crick discovered the double helix made a giant news history of science. They both achieved this experiment by sharing both methods and ideas. They concluded that each strand of the DNA molecule was a temple to other.https://profiles.nlm.nih.gov/SC/Views/Exhibit/narrative/doublehelix.html -

Human Genome is fully sequenced
In 2003, it was declared that the human genome project was complete within 2 years ahead from their schedule a research project that determines the sequence of the human genome and to identify the gene that it involves. The human project is what help us more detailed inform about chromosomes.
