1.     Heredity and Evolution Introduction: Basic unit of life is cell. Controlling center of cell is nucleus. Inside nucleus there are chromosomes. Chromosomes are made up of DNA. Segment of DNA is called as gene. ✱ Heredity and Hereditary Changes: Heredity: Transfer of characters from one generation to another via genes. Johann Gregor Mendel - Father of modern genetics. Hugo de Vries - Mutation Theory (1901). Walter and Sutton - Observed paired chromosomes in cells of grasshopper. Ostwald Avery, Maclyn McCarthy and Colin MacLeod - Except viruses, all living organisms have DNA as genetic material (1944). Francois Jacob and Jack Monad - Proposed a model for process of protein synthesis. Science of heredity is useful for: Diagnosis, treatment and prevention of hereditary disorders. Production of hybrid varieties of animals and plants. In industrial processes in which microbes are used. ✱ Structure of DNA (Deoxyribo Nucleic Acid) Chromosomes are made up of DNA. Chromosomes are a...
