Discuss the chain of events that led to the discovery of DNA as the heritable substance and the discovery of the structure of DNA. Ans> The chain of events led to the discovery of DNA as the heritable substance and the discovery of the structure of DNA. In the late nineteenth century‚ a German biochemist Friedrich Miescher found the nucleic acids which are long-chain polymers of nucleotides‚ and are made up of sugar‚ phosphoric acid‚ and several nitrogen-containing bases.

thalidomide‚ under a restricted access system‚ for the treatment of leprosy[->6] (Hansen’s Disease). As of 2001‚ thalidomide was in clinical trials as a way of treating some cancers and some conditions in AIDS. Australian researchers began a trial of the controversial drug in April 2002‚ involving 224 cancer patients over a two-year period. The study found thalidomide sparked a doubling of the number of 20 T cells[->7] in patients. This allowed their own immune system[->8] to attack and fight the cancer
