Importance of Chemistry Chemistry is an important branch of science. Chemistry deals with the matter that form our environment and the transformation that the matter undergoes. Chemistry is therefore‚ useful in understanding the changes taking place in the constituents of the environment and the resulting advantages. Chemistry is connected with composition‚ structure and properties of the matter. In fact it is a science of atoms and molecules. Organic chemistry‚ inorganic chemistry‚ physical chemistry‚ analytical

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause
