Diagnostic Quizzes & Trivia

Molecular genetics is the branch of biology in which the scientific study of the structure and function of genes are done at a molecular level and engages methods of both molecular biology and genetics. To understand and diagnose genetic disorders, variations, mutations, its necessary to know about Molecular Genetics. This quiz has been designed to test your knowledge about the diagnosis of genetic diseases. Read the questions carefully. And learn more!
