The work of which of the following scientists demonstrated the mutagenic nature of radiation? A - HSC - SSCE Biology - Question 6 - 2018 - Paper 1

The scientist whose work demonstrated the mutagenic nature of radiation is C. Tatum. In the 1940s, Tatum and his colleagues conducted experiments with the fungus Neurospora crassa, which provided critical insights into how radiation can lead to mutations in organisms. Their research illustrated the relationship between genetic mutations and external factors such as radiation, laying the foundation for the field of molecular genetics.
