Theodor Heinrich Boveri (October 12, 1862–October 15, 1915) was a German biologist whose work with sea urchins showed that it was necessary to have all chromosomes present in order for proper embryonic development to take place. Events 539 BC - The army of Cyrus the Great of Persia takes Babylon. Year 1862 was a Common year starting on Wednesday (link will display the full calendar of the Gregorian calendar (or a Common year starting on Monday Events 533 - Byzantine General Belisarius makes his formal entry into Carthage, having conquered it from the Year 1915 ( MCMXV) was a Common year starting on Friday (link will display the full calendar of the Gregorian calendar (or a Common year Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. A biologist is a Scientist devoted to and producing results in Biology through the study of Organisms Typically biologists study organisms and their relationship Sea urchins are small globular spiny sea cat animals composing most of class Echinoidea. A chromosome is an organized structure of DNA and Protein that is found in cells. Embryogenesis is the process by which the Embryo is formed and develops This discovery was an important part of the Boveri-Sutton chromosome theory. The Boveri-Sutton chromosome theory is that Mendelian alleles are located on Chromosomes. His other significant discovery was the centrosome (1888), which he described as the especial organ of cell division. In Cell biology, the centrosome is an Organelle that serves as the main Microtubule organizing center (MTOC of the animal cell as well Boveri also had discovered a phenomenon of chromatin diminution in early embryonic development of nematode Parascaris.
He also reasoned that a cancerous tumor begins with a single cell in which the make up of its chromosomes becomes scrambled, causing the cells to divide uncontrollably. Cancer (medical term Malignant Neoplasm) is a class of Diseases in which a group of cells display uncontrolled The cell is the structural and functional unit of all known living Organisms It is the smallest unit of an organism that is classified as living and is often called
It was only much later in the twentieth century that leading researchers came to believe that Boveri may have been correct.
