Experiments with peas lead Austrian monk Gregor Mendel to discover that certain traits are inherited in varying proportions, depending on whether they are recessive or dominant.
-
In 1869 Friederick Miescher extracts what comes to be known a DNA from the nuclei of white blood cells.
-
In 1928 Fredrick Griffith discovered that bacteria is capable of transferring genetic information through a process known as transformation.
-
Created and analyzed mutants of neurospora. Their point was to show how genes direct the synthesis of enzymes that control metabolic processes.
-
Employs bacteriophages, a type of virus that invades bacteria. Max Delruck begins the study of bacterial genetics.
-
In 1944 they identify DNA as the "transforming principle" responsible for specific characteristics in bacteria.
-
Discover the molecular structure of DNA.
-
Discovers regularity in porpotions of DNA bases for different species.
-
Discover independent functions of viral protein and nucleic can be used in growth of bacteriophage
-
Discovered that the chemical structure of DNA meets the unique requirements for a substance that encodes genetic information.
-
Arthur Kornberg crystallizes DNA polymerase, the enzyme required for synthesizing DNA.
-
Discovered that DNA replication is semiconservative. In semiconservative DNA each of the two double stranded helixes consist of one strand from the original helix and one newly synthesized strand.
-
Discovered the first triplet a sequence of 3 bases of DNA that codes for one of the 20 amicno acids that serve as building blocks of protein
-
He invents recombinant DNA technology - a way in which genetic material from one organism is artificially introduced into the genome of another organism.
-
They develop recombinant DNA technology, showing that genetically engineered DNA molecules may be cloned in foreign cells.
-
Kary Mullis concieves and helps develop polymerase chain reaction (PCR), a technology for rapidly multiplying fragments of DNA.
