Molecular genetics is a fundamental theory that determines the structure and function of genes in an organism genome by using an investigative approach. It is based on the combination of fields in biology like biochemistry, classical Mendelian inheritance, cellular biology, and biotechnology. Molecular biology. Molecular geneticists are always eager to about how genes control the development and function of organisms. The identification of disease-related genetic abnormalities by mapping genetic genome, analyzing genetic changes in tumors and developing new procedures and tests are the some of credits of Molecular Genetics.
The correct answer is "Emory Bogardus's research on social distance". Emory Bogardus designed a Social Distance Scale for measuring attitudes toward racial and ethnic groups. Bogardus believed that the more prejudiced is a person against a race or ethnic group the less he would like to interact with someone that belongs to that group.
