studying plant structure under micerscope
He was the first to study the structure of the plant under a microscope. Thus he was the first to realize that the plant was made of different cells and that the nucleus was important. http://www.vuvox.com/collage/detail/0532e10418?item=248640 -
All living things
Theodor Schwann, took Mathias studying and add an important part to it, he mentioned that, all living things are made out of cells and their products. http://www.vuvox.com/collage/detail/0532e10418?item=248640 -
Dominant Genes
After Studying crossing pea plants, mendel manadge to make histroy regarding the feild of genetics. Each gene is made up of two alleles, the dominant and the recessive. http://library.thinkquest.org/C0118084/History/Mendel.htm -
Identification of Nuclein
Nuclein (aka DNA) was identified by Friedrich Miescher. He said that the DNA was acidic and that it was found in the Nuclei. However back then people thought that it was useless. http://www.bio.davidson.edu/people/kahales/301Genetics/timeline.html -
Chromosomes
As technology advanced throughout the past years, Walther Flemings managed to give us an accurate image of cell divisions. More importantly he discovered small fibrous networks to be named chromosomes. http://www.nature.com/scitable/topicpage/developing-the-chromosome-theory-164 -
Disease
A human disease is first attributed to genetic causes ("inborn errors of metabolism") http://www.bio.davidson.edu/people/kahales/301Genetics/timeline.html -
Linkage map
First DNA linkage map was drawn by an undergraduate named Alfred Sturtevant while working with T.H morgan. http://www.bio.davidson.edu/people/kahales/301Genetics/timeline.html -
Proteins
In addition to governing the expression of hereditary characteristics, genes direct the manufacture of proteins that control the basic metabolic functions, which characterize life itself. http://www.genomenewsnetwork.org/resources/timeline/1941_Beadle_Tatum.php -
Fingerprints
DNA fingerprinting, gene therapy, and genetically modified foods come onto the scene. http://www.bio.davidson.edu/people/kahales/301Genetics/timeline.html
