Gregor Mendel experimented with the genetics of pea plants for eight years (1856 - 1863). Through his experiments he discovered genetic similarities among pea plants. He published his findings in 1865. Mendel's experiments are known as the Laws of Inheritance.
-
Boveri discovered the centrosome, which is the main microtubule organizing center of an animal cell. It also serves as the regulator of cell progression in an animal cell.
-
Discovered chromosomes make up the basis of heredity, and in meiosis, the reduction of chromosomes relates to Mendel's laws of inheritance.
-
Present findings that chromosomes are related to factors in heredity relating to the work of Gregor Mendel.
-
Theodor Boveri studied sea urchins to find out that having all chromosomes present is necessary for the development of an embryo to take place.
-
Frans Janssen discovered that genes cross over during meiosis.
-
Developed ideas, and brought together proof of heredity, genetic linkage, chromosomal crossing over and non-disjunction.
-
Barbara McClintock developed the theory for transposition, the position change of genes on chromosomes.
-
McClintock discovered/developed to understand the expression and the suppression of genetic information through generations.
-
Crick and Watson find the molecular structure of dna called the double helix
-
Francis Crick finds adn reveals the use of messenger rna which transports genetic information.
