Document Summary
Concerned primarily with the understanding that biological properties are transmitted from parent to offspring. Genetics includes heredity, molecular nature of the genetic material, the ways in which genes control life functions, and the disruption and behaviour of genes in populations. 1856-1863 - gregor mendel analyzed quantitatively the results of crossing pea plants that varied in easily observable characteristics. Mendel had discovered fundamental principles of heredity (the foundation of modern genetics) 1972 paul berg constructed the first recombinant dna molecule in vitro (work with mutant genes so that they compare the differences with normal genes) 1973 herb boyer, stanley cohen first used a plasmid to clone dna. 1986 kary mullis developed the polymerase chain reaction (pcr) a technique for amplification of selected dna segments without cloning. Hypothetic-deductive method of investigation consists of making observations, forming hypotheses to explain the observation, making experimental predictions based on hypotheses ad finally testing the predictions (for refinement purposes).
